Answer:
x = 25
Step-by-step explanation:
Given:
- ∠A = ∠B (Vertically opposite angles)
- ∠A = (7x - 8)°
- ∠B = (6x + 17)°
Since ∠A is equivalent to ∠B...

Open the parenthesis:

Add 8 both sides:

Simplify both sides:

Subtract 6x both sides:

Simplify both sides:

Answer:
85° (C).
Step-by-step explanation:
35° should go over to the other side of the line:
180 - 35 = 145°
Find angle 1:
145 + 130 + angle 1 = 360°
360° = 275° + angle 1
angle 1 = 360 - 275
angle 1 = 85°
85° which is C is the answer.
