Question

What is the measure of the highlighted (middle) angle, in degrees?

Answer 1

2x+5x+67.3=180
7x=112.7
X=16.1
16.1 times 5
80.5

Answer 2

Explanation:

5x + 2x + 67.3° = 180° { being linear pair }

7x = 180° - 67.3°

7x = 112.7°

x = 112.7°/7

x = 16.1°

Now

5x = 5 * 16.1 = 80.5°

Hope it will help :)
