the lengths in inches of the legs XY and XZ are, 5.53 & 7.36 .
What is Pythagorean theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
here, we have,
in right triangle ,XYZ, the length of the hypotenuse YZ=85 and tanZ=3/4.
so, we get,
let, the sides= 3x & 4x
now, by Pythagorean theorem,
9x^2 + 16x^2 = 85
x=1.84
hence, the lengths in inches of the legs XY and XZ are, 5.53 & 7.36 .

Answers:
AC = 221.37 feet
BC = 181.34 feet
The values are approximate.
=========================================================
Explanation:
Focus on triangle ACD for now.
The 67 degree angle adjacent to angle D helps us find that angle D = 180-67 = 113 degrees.
Let's find the missing angle C.
A+C+D = 180
55+C+113 = 180
C+168 = 180
C = 180-168
C = 12
Now we can use the Law of Sines to find side d, which is opposite angle D. This is the segment AC.
[tex]\frac{\sin(C)}{c} = \frac{\sin(D)}{d}\\\\\frac{\sin(12)}{50} = \frac{\sin(113)}{d}\\\\d\sin(12) = 50\sin(113)\\\\d = \frac{50\sin(113)}{\sin(12)}\\\\d \approx 221.369 190\\\\d \approx 221.37\\\\[/tex]
Segment AC is roughly 221.37 feet long.
Keeping our attention on triangle ACD, let's find side 'a'. This is the segment CD.
[tex]\frac{\sin(C)}{c} = \frac{\sin(A)}{a}\\\\\frac{\sin(12)}{50} = \frac{\sin(55)}{d}\\\\a\sin(12) = 50\sin(55)\\\\a = \frac{50\sin(55)}{\sin(12)}\\\\a \approx 196.995 186\\\\[/tex]
Segment CD is roughly 196.995186 feet long.
----------------------------------------------
Now move onto triangle BCD.
Use the sine ratio to determine side BC.
[tex]\sin(\text{angle}) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin(\text{D}) = \frac{\text{BC}}{\text{CD}}\\\\\sin(67) \approx \frac{\text{BC}}{196.995186}\\\\\text{BC} \approx 196.995186*\sin(67)\\\\\text{BC} \approx 181.335025\\\\\text{BC} \approx 181.34\\\\[/tex]
Segment BC is roughly 181.34 feet long.

What is the formula for finding the midpoint of a segment? Circle your choice.
Answer:
Choice D is the correct answer. (I assure you)
{Answer choice B is incorrect.}
The formula for finding the midpoint of a segment is :
( (x₁ + x₂)/2, (y₁ + y₂)/2). Hence, Option D is correct.
Use the concept of coordinates defined as:
A pair of numbers that describe the exact position of a point on a cartesian plane by using horizontal and vertical lines are called the coordinates.
Consider two opposite points of a segment (x₁, y₁) and (x₂, y₂).
Then x coordinate of the midpoint of the line joining this point is :
(x₁ + x₂)/2
And y coordinate of the midpoint of the line joining this point is :
(y₁ + y₂)/2
Therefore,
The coordinate of the midpoint of this segment is ( (x₁ + x₂)/2, (y₁ + y₂)/2)
Hence, Option D is the correct coordinate to find the midpoint.

A linear function is a function with the form f(x) = ax' + b. It looks like a regular linear equation, but instead of using y, the linear function notation is f(x). To solve a linear function, you would be given the value of f(x) and be asked to find x.

The length of the third side is a-2.
Given that:
Perimeter of triangle: 6a + 3
Length of first side: 2(a+3)
Length of second side: 3a -1
Let the length of the third side of the triangle be x.
Then as perimeter of a triangle is sum of lengths of all 3 sides of the triangle, thus we have:
Thus we have length of the third side as a -2.

15. What is the value of the expression below?
Answer:
-4 3/8 thus A. is the answer
Step-by-step explanation:
Simplify the following:
-7/2 - (5/8 + 1/4)
Put 5/8 + 1/4 over the common denominator 8. 5/8 + 1/4 = 5/8 + 2/8:
-7/2 - (5/8 + 2/8)
5/8 + 2/8 = (5 + 2)/8:
-7/2 - ((5 + 2)/8)
5 + 2 = 7:
-7/2 - 7/8
Put -7/2 - 7/8 over the common denominator 8. -7/2 - 7/8 = (4 (-7))/8 - 7/8:
(4 (-7))/8 - 7/8
4 (-7) = -28:
(-28)/8 - 7/8
-28/8 - 7/8 = (-28 - 7)/8:
(-28 - 7)/8
-28 - 7 = -(28 + 7):
(-(28 + 7))/8

Triangle P'Q'R' is larger because it is dilated by a scale factor of 1.5, which is greater than 1, meaning it will be bigger than triangle PQR.2.
Segment P'Q' = 1.5 x 5 = 7.5It will be 7.5 because after dilation, each of the sides of the original triangle is multiplied by the scale factorPQ x 1.5 = P'Q'P'Q' = 5 x 1.5P'Q' = 7.5Write an equation in point-slope form of the line that passes through the point (-6,6) and has a slope of m=3/2

Answer:
[tex]y-6=\frac{3}{2} (x+6)[/tex]
Step-by-step explanation:
Hi there!
We are given a point (-6, 6) and a slope of [tex]\frac{3}{2}[/tex]
We want to write the equation of the line that contains this point and slope in point-slope form
Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
As we are already given everything we need, we can simply substitute the values into the formula
Starting with the slope, substitute 3/2 as m into the equation:
[tex]y-y_1=\frac{3}{2} (x-x_1)[/tex]
Now substitute -6 as [tex]x_1[/tex] and 6 as [tex]y_1[/tex]
[tex]y-6=\frac{3}{2} (x--6)[/tex]
Simplify:
[tex]y-6=\frac{3}{2} (x+6)[/tex]

(HELP PLS) Monica is building her dream home. It will have a total floor area of 2.150 sq. ft.
a. If Monica wants the living room to be 30% of the total area, what would the living room's area be?
b. The house Monica currently lives in has only 65% of the floor area of her dream home. What is the floor area of her current home?
The living room area of Monica's home is 0.645 ft².
The floor area of her current home is 1.3975 ft²
How to find percentage of an area?
The total floor area of Monica's dream home should be 2.150 ft².
Monica wants the living room to be 30% of the total area. Therefore, the living room area will be as follows:
living room area = 30 / 100 × 2.150 = 64.5 / 100 = 0.645 ft²
Her current house has only 65% of the floor area of her dream house. Therefore, the floor area of her current home is as follows:
Floor area of her current home = 65 / 100 × 2.150
Floor area of her current home = 139.75 / 100
Floor area of her current home = 1.3975 ft²

Step-by-step explanation:
Remark
Notice that the symbol of the angle above 6x + 5y is the symbol for a right angle. Since all three angles are on a straight line, they are either the supplement of a right angle or a right angle.
Givens
right angle
The right angle's supplement (which is also 90degrees) of (6x + 5y)
10y = 90 degrees which a corresponding equal angle to (6x + 5y)
Solution
10y = 90 See remarks for reason. Divide by 10
10y/10 =90/10
y = 9
6x + 5y =90
6x + 5*9 = 90 Combine
6x + 45 = 90 Subtract 45 from 90
6x = 90 - 45 Combine
6x = 45 Divide both sides by 6
6x/6 = 45/6
x = 7.5

A 2-liter container holds more than a 3,000-milliliter container. True or false?
To consider whether this statement is true or not
⇒ must determine the number of milliliters in a liter
⇒ 1 Liter = 1000 milliliter
To compare both containers, lets set both containers in terms of milliliters
Container 1 --> 2 Liter Capacity --> 2000 milliliterContainer 2 --> 3000 milliliterBy looking at the data
⇒ the 3000-milliliter container holds more than the2-liter container
Thus, the statement: A 2-liter container holds more than a 3,000-milliliter container
⇒ False
Answer: False
Hope that helps!
Answer:
False because 2 liters = 2,000 milliliters. Therefore that is not possible.

Step-by-step explanation:
What is the rate of change in y with respect to x in the function x + 5y = 10?
Answer:
-1/5
Step-by-step explanation:
let's put the function in slope intercept form (y = mx + b).
x + 5y = 10
y = - (1/5)x + 2
when the function is in slope intercept form, (m) is the rate of change or the slope.
therefore, the rate of change -1/5
