Answer:
132°
Step-by-step explanation:
∠AOB = ∠EOD = 3x ( vertical angles )
∠AOB + ∠BOC = 90, that is
3x + 0.5x + 34 = 90
3.5x + 34 = 90 ( subtract 34 from both sides )
3.5x = 56 ( divide both sides by 3.5 )
x = 16
∠AOE + ∠EOD = 180 ( straight angle )
∠AOE + 3x = 180
∠AOE + (3 × 16) = 180
∠AOE + 48 = 180 ( subtract 48 from both sides )
∠AOE = 132°
Answer:
x = -6
Step-by-step explanation:
- 1/3 x + 12 = -2x + 2
(- 1/3 x + 1/3) + 12 = (-2x + 1/3) + 2
12 = - 1 2/3x + 2
12 -2 = - 1 2/3x (+ 2 - 2)
10 = - 1 2/3x
x = -6
