Question

HELP PLEASE!!!!!!!!​

Answer 1

40° = m<AOB

Explanation:

[8x - 28] + [3x + 4] = 108 ↷

-24 + 11x = 108 [Combine like-terms]

-24 + 11x = 108

+24 + 24

________________

11x = 132; 12 = x [plug this back into the m<AOB formula to get 40°]

3[12] + 4 = 40

Answer 2

AOB = 40 degrees

Explanation:

The two smaller angles, AOB and BOC, add up to form AOC. That means that the angles of AOB and BOC sum up to the angle of AOC

`3x+4+8x-28=108\\11x=132\\x = 12\\\\3(12)+4=AOB\\AOB = 40 degrees`
