Question

Find the measure of ∠x.
A) 26°
B) 30°
C) 36°
D) 39°

Answer 1

the answer is C

Explanation:

Answer 2

C) 36°

Explanation:

The sum of the exterior angles of a triangle add to 360 degrees

The exterior angle with x is (180-x) because it makes a straight line

72+144 +(180-x) = 260

Combine like terms

396-x = 360

Subtract 396 from each side

396 -396 -x = 260-296

-x = -36

Multiply by -1

x=36
