What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.

Answers

Answer 1

Answer:

That is a 30 60 90 triangle.

In such a triangle the "middle" size = short side * sq root (3)

height = 5 * sq root (3) = 8.6602540378

Area = (1/2) * 5 * 8.6602540378

Area = 2.5 * 8.6602540378

Area = 21.6506350946 square centimeters

Answer 2

Answer:

A=24√3

Put In Decimal Form:41.5692193817^3

Step-by-step explanation:

4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.

A=1/2(4)(4√3)

2(12√3)

24√3

What is a parallelogram?

In geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

The proof is as follows :-

AD≅BC (Given)

AD║BC (Given)

∠DAC and ∠BCA (alternate angles)

∠DAC ≅ ∠BCA (alternate angle)

AC ≅ AC (common)

ΔDAC ≅ ΔBCA (SAS rule)

AB ≅ CD (CPCT)

Hence,

ABCD is a parallelogram (by the definition of parallelogram)

Hence, proved.

Answer:

y=4x-5

Step-by-step explanation:

the slope intercept equation is y=mx+b

m=slope and b=y intercept

the slope is the change in y over the change in x and as y goes up 8 x goes over one 8/2=4 so the slope (m) is 4

The y intercept is at (0,-5) so b is -5

if we add it all together we get that the slope intercept equation is y=4x-5

Write the equation of the line in fully simplified slope-intercept form.

Answers

y= slope x + y intercept
the answer is y=4/5x+8

Answer:

y=4/5x+8

Step-by-step explanation:

in order to find the slope intercept form of a line the first step you have to take is finding where the line meets the y-axis

in this case it would be at (0,8)

so therefore 8 would be your y-intercept (which we label as B)

then in order to find the slope, what i do is find the next point in the middle of the graph (-5,4)

and then i find the distance between the y-intercept and the next point

and in order to do this i first take 8 and subtract by 4 in order to get to (0,4)

and then it moves to the left so i also subtract -5 because the next point is located on (-5,4)

so when doing this it creates our equation of y=mx+b

and that turns into y=4/5x+8

desmos is also a website that can help you with graphing and visualizing things out as well and can also be useful for trial and error when it comes to slopes and graphs and what not.

The smallest angle in a triangle measures 9 degrees less than the middle angle. The largest angle is 26 degrees more than 3 times the measure of the smallest angle.

Answers

Answer:

Step-by-step explanation:

A+B+C = 180°

A ≤ B ≤ C

B = A+9

C = 3A+26

A+B+C = A + (A+9) + (3A+26) = 5A + 35° = 180°

5A = 145°

A = 29°

B = A+9 = 38°

C = 3A+26 = 113°

If asia is 10 years older than rani the sum of their age is 200

Answers

Let Asia's and Rani's age be "x"

Since Asia is 10 years bigger Asia will be "x+10"

Asia's Age + Rani's Age = 200

x + x + 10 = 200

2x + 10 = 200

2x = 200 - 10

2x = 190

x = 190

-----

x = 95

Asia = x + 10

95 + 10

105

Rani's age is 95 and Asia's Age is 105

Which of the following shows a translation of f(x) two units down?
A. f(x + 2)
B. f(x) + 2
C. f(x – 2)
D. f(x) – 2

Answers

Answer: D. f(x)-2

Step-by-step explanation:

Changes insides the parenthesis translate left and right. If it is [+] a number, then it is moving to the left. If it is [-] a number, then it is moving to the right.

Changes outside the parenthesis translate up and down. If it is [+] a number, then it is moving upward. If it is [-] a number, then it is moving downward.

----------------------------------------------------------------------------------------------------

Given

Translate f(x) 2 units downward

Solve

According to the rules, it should be -2 units outside of the parenthesis

Therefore, it should be f(x)-2

Independent: surface area of walls
Dependent: paint used

Basically, independent means that this data should not need to change. Dependent typically depends on what is given in the independent. Looking back at the example, if the surface area of the walls is large, then a lot of paint would be necessary. The opposite would occur for a smaller surface area in the walls.

2/3x + 1/4 = 46/6x - 1/3

Answers

Answer:

x = 1/12

Step-by-step explanation:

2/3x + 1/4 = (8x+3) /12 (create equivalent fractions with a denominator of 12)

23/3x - 1/3 = (23x - 1) /3 *(46/6x = 23/3x)

8x + 3 = 23x - 1

12 3

now cross-multiply:

3(8x + 3) = 12(23x - 1)

24x + 9 = 273x - 12

9 = 252x - 12

21 = 252x

x = 21/252 which reduces to 1/12
