Answer 1

Answer:

Step-by-step explanation:

Given the following angle

We want to find angle AOB

∠AOC = 108°

∠AOB = 3x+4

∠BOC =8x−28 ​

Check attachment for understanding

From the attachment, we notice that the sum of angle AOB and angle BOC equals to angle AOC.

∠AOB + ∠BOC = ∠AOC

3x + 4 + 8x —28 = 108

3x + 8x + 4—28 = 108

11x — 24 = 108

11x = 108 + 24

11x = 132

x = 132/11

x = 12°

∠AOB = 3x+4

∠AOB = 3(12) + 4

∠AOB = 36+4

∠AOB =  40°

Extra

∠BOC = 8x−28

∠BOC = 8(12)−28

∠BOC = 96−28

∠BOC = 68°
