Answer:
Other two angles of quadrilateral measures 18° and 39°Step-by-step explanation:
Given that a quadrilateral has two angles that measure 222° and 81°.
Let other two angles of quadrilateral be 6x and 13x. We know that sum of all the angles of quadrilateral is 360°.
➝ 222 + 81 + 6x + 13x = 360°
➝ 303 + 19x = 360°
➝ 19x = 360° - 303
➝ 19x = 57
➝ x = 57/19
➝ x = 3
Hence,
6x = 6(3) = 18° 13x = 13(3) = 39°∴ Other two angles of quadrilateral measures 18° and 39°
Answer:
Measurement of other two angles are 39° and 19°
Step-by-step explanation:
Given :-
Quadrilateral has two angles of measurement 222° and 81° and the other two angles are in ratio of 6:13To find:-
The measurement of other two anglesSolution:-
Let the value of other two angles be 6x and 13x
We know , the sum of angle inside a quadrilateral is 360°
222° + 81° + 13x + 6x = 360°
19x = 360° - 303°
x = 3
So , the value of other two angles are
13 × 3 = 39°
6 × 3 = 18°

give your anwser in standard form
Answer:
4.9 × [tex]10^3[/tex]
Step-by-step explanation:
Start by doing what is in the paranthesis from right to left.
[tex]9 * 10^2 = 900[/tex]
and
[tex]4 * 10^3 = 4000[/tex]
So if we add them we get:
[tex]900 + 4000 = 4900[/tex]
Now to put it into standard form we just put a decimal to the right of the first number and see how many times we need to move right in order to make the number. In this case it's 3 times so we tack on × [tex]10^3[/tex]
So our answer is:
[tex]4.9[/tex] × [tex]10^3[/tex]

How to solve 3x - 1/2 = 8 1/2 please no links and do it step by step
Answer:
[tex]x=\frac{3}{2}[/tex]
Step-by-step explanation:
Step 1. Put each term in [tex]3x-\frac{1}{2}[/tex] over the common denominator 2.
[tex]\frac{6x}{2}-\frac{1}{2}[/tex]
Therefore we have [tex](\frac{6x}{2}-\frac{1}{2})=4[/tex]
Step 2.
Combine [tex]\frac{6x}{2}-\frac{1}{2}[/tex] into a single fraction.
[tex]\frac{6x-1}{2}[/tex]
Therefore we have [tex](\frac{1}{2}(6x-1))=4[/tex] or [tex]\frac{6x-1}{2}=4[/tex]
Step 3.
Multiply both sides by a constant to simplify the equation.
Multiply both sides of [tex]\frac{6x-1}{2}=4[/tex] by 2:
[tex]\frac{2*(6x-1)}{2}=4*2[/tex]
Step 4.
Cancel the common terms in the numerator and denominator of [tex]\frac{2*(6x-1)}{2}[/tex]
Then we get [tex]\frac{2}{2}*(6x-1)[/tex] which simplifies to [tex](6x-1)[/tex]
So all together we have [tex](6x-1)=2*4[/tex]
Step 5.
Multiply 2 and 4 together and remove the parenthesis.
[tex]6x-1=8[/tex]
Step 6.
Isolate terms with the variable x to the left hand side.
So add 1 to both sides:
[tex]6x+(1-1)=8+1[/tex]
Evaluate [tex]1-1=0[/tex] which cancels out
Step 7.
Add the like terms on the right side:
[tex]6x=9[/tex]
Step 8.
Divide both sides by a constant to simplify the equation.
Divide both sides of [tex]6x=9[/tex] by 6.
[tex]\frac{6x}{6} =\frac{9}{6}[/tex]
Any non-zero number divided by itself is 1.
[tex]x=\frac{9}{6}[/tex] which simplifies to [tex]x=\frac{3}{2}[/tex]
What is the area of a square enclosure that uses 320 meters of fencing?
Answer:
A = 6400 m²
Step-by-step explanation:
the sides s of a square are congruent , then
s = 320 ÷ 4 = 80 m
tahe area (A) of a square is calculated as
A = s² = 80² = 6400 m²
The required area of square, having side 80 meters, is 6400 square meters.
What is square ?A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at a straight angle or 90 degrees.
Given that,
The length of fencing enclosure a square = 320 meters,
Let the side of the square is a meter,
According to given condition, perimeter of square,
4a = 320
a = 80
Since, the area of square having side a, is a²
Area = a²
Area = (80²)
Area = 6400 square meters.
The area of square, having side 80, is 6400 square meters.

Write an inequality for the given graph! Please help!
Answer:
y < 1/2 x - 3
Step-by-step explanation:
The line crosses the y-axis (up and down numbered axis) at -3. That's the - 3 in the equation. If you look very carefully, closely, you can see that the line, from there, goes UP1 and OVER2 to get to the next point (and the next point and the next point) This is the slope, it goes in front of the x, here it is UP1 and OVER2 and is written 1/2.
The line is dashed so the symbol is < "less than" WITHOUT the line mark underneath it; also because the shading is BELOW the dashed line we use < "less than" and not > "greater than"

If (8,b) Is a solution to the equation represented by the graph below, what is the value b?
Answer:
b= -18
Step-by-step explanation:
See attached image.
Formulate the equation for the line by calculation the slope and adding the y-intercept, as shown. The y-intercept if the value of y when x = 0. The equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept. Note that this b is not the same b in the question (8,b). The b in the question may be calculated once the equation is found: y = -3x+6, where -3 is the slope and 6 is the y-intercept (0,6).
Use x = 8 in this equation. y = -3(8)+6, y = -18
The point is (8,-18), so b is -18.

The mean of 4, 10, 3, 6, a, 9 and 10 is 7, find the value
of a
Answer:
The value of a is 7.
Step-by-step explanation:
To calculate mean, add all of the numbers in the set and divide by the number of terms in said set. There are 7 numbers in this set, so the equation can be set up as follows.
(4 + 10 + 3 + 6 + a + 9 + 10)/7 = 7
Simplify the terms on the top.
(42 + a)/7 = 7
Multiply both sides by 7.
42 + a = 49
Subtract both sides by 42.
a = 7.
Proof:
(4 + 10 + 3 + 6 + a + 9 + 10)/7 = 7
Substitute variable.
(4 + 10 + 3 + 6 + 7 + 9 + 10)/7 = 7
Add in the parenthesis.
49/7 = 7
Divide.
7 = 7.

Angles ABC and CBD are complementary - they add up to 90°. This means
(4x + 52°) + (8x - 10°) = 90°
Solve for x :
12x + 42° = 90°
12x = 48°
x = 4°
It follows that angle CBD has measure
4 • 4° + 52° = 16° + 52° = 68°

find angle CAB
a. 32
b. 26
c. 64
d. 58
Answer:
b. 26°Step-by-step explanation:
ABE is tangent to the circle then m∡OBE = m∡OBD = 90
Then m∡OBD = 90 - 58 = 32
In the triangle DAB :
m∡CAB = m∡DAB = 180 - [m∡BDA + (m∡DBA)]
= 180 - [ 32 + (90 + 32)]
= 180 - [ 32 + ( 122) ]
= 180 - [ 154 ]
= 26
Answer:
B) 26°
Step-by-step explanation:
Finding ∠OBD
∠OBA = ∠OBE = 90° [tangent to the circle]∠OBE - 58° = ∠OBD∠OBD = 90° - 58°∠OBD = 32°Then, ∠ADB = ∠OBD = 32° (angles opposing equal sides OB and OD, both of which are radii of the circle.
Finding ∠CAB
∠CAB + ∠ADB + ∠OBD + ∠OBA = 180° [Angle Sum Property]∠CAB + 32° + 32° + 90° = 180°∠CAB + 154° = 180°∠CAB = 26°which is equivalent to 12
