Question

Anyone get this please help me

Answer 1

AOB = -8x + 68

Explanation:

AOC = 40°

BOC = 8x - 28

Angle Addition Theorem:

AOB + BOC = AOC

AOB + (8x - 28) = 40

AOB + (8x - 28) + 28 = 40 + 28

AOB + 8x - 8x = 68 - 8x

AOB = -8x + 68

AOB + BOC = AOC

(-8x + 68) + (8x - 28) = 40

-8x + 8x + 68 - 28 =40

0x + 40 = 40

40 = 40
