Question

SOLVE FOR x IN THE DIAGRAM BELOW

Answer 1

Well, the base of it is a 180° angle and the middle angle is 80°. That leaves 3x and 2x.

3 x 20 = 60
2 x 20 = 40
60 + 40 = 100
100 + 80 = 180
180°

I am probably wrong but have a good day :)

Answer 2

3x+2x+80=180
5x+80=180
5x=100
ANSWER IS x=20

So to check if the answer is correct:
Angle 3x is 3x20 = 60 degrees
Angle 2x is 2x20= 40degreee

60+40+80= 180 degrees
