Answer:
x = 20°
Step-by-step explanation:
The angle opposite to 3x + 20 is also 3x + 20 (opposite interior angles)
The angle opposite to 5x is also 5x (opposite interior angles)
Solve:
Set up the equation by adding all the angles. The sum of these angles should equal 360.
- (3x + 20) + (3x + 20) + (5x) + (5x) = 360
- 16x + 40 = 360
- 16x = 320
- x = 20
x = 20°
