Answer:
x = 12
The measure of Angel A and Angle B = 144°
Step-by-step explanation:
Angle ∠ A= 10x+24∘
Angle ∠B=6x+72 ∘
Angle A and Angle B are Alternate interior angles hence, they are equal to each other.
Hence:
10x + 24 = 6x + 72
Collect like terms
10x - 6x = 72 - 24
4x = 48
x = 48/4
x = 12
The measure of ∠ A= 10x+24∘
=( 10(12) + 24)°
=( 120 + 24)°
= 144°
The Measure of Angle ∠B=6x+72 ∘
=( 6(12) + 72)°
= (72 + 72)°
= 144°
