Question

find the measure of the exterior angle

Answer 1

• $\sf{ 108°}$

Step-by-step explanation:

As we know that,

The sum of two corresponding interior angles =exterior angle

According to the question,

• (a+10)+44=2a

• a+10+44=2a

• a+54=2a

• 2a-a=54

• a=54

Hence,

The exterior angle =2a=2×54=108°

Answer 2

2a= (a+10) + 44 - exterior angle thm.
2a= a + 54 - simplify
a= 54- subtract a from both sides of the equation

SUBSTITUTION
2(54)= 108 degrees
