Answer:
Given ABCD be a parallelogram
Then, AD // BC and AB is a transversal.
Because of the sum of the interior angles on the same side of the transversal is 180°
So, ∠A + ∠B = 180°
∴ Angle A and angle B are supplementary.
<u>Also</u>,
AB // CD and CB is a transversal.
Because of the sum of the interior angles on the same side of the transversal is 180°
So, ∠B + ∠C = 180°
∴ Angle B and angle C are supplementary.
Answer:
Step-by-step explanation:
The triangles UVW, UVA and UAW, since all three are right angles and have the same combination of angles, meaning the existence of proportionality between corresponding lengths. That is:
, 
, 
Hence, the complete similarity statement is:
Hey :)
x= -12
Use the distributive property to multiply −4 by 2x+13
−8x−52=3x+80
Subtract 3x from both sides
−8x−52−3x=80
Combine −8x and −3x to get −11x
−11x−52=80
Add 52 to both sides
−11x=80+52
Add 80 and 52 to get 132
−11x=132
Divide both sides by −11
x= 132/-11
Divide 132 by −11 to get −12
x=−12
Hope this helps :)
