Question

determine the angle of the following triangle
​

Answer 1

Answer:

120 degrees

Step-by-step explanation:

if you add the two opposite interior angles you get the exterior angle

(36+2x)=5x

36=5x-2x

3x=36

3x/3=36/3

x=12 degrees

5x=60 degrees

your angle will be 180 degrees -60 degrees=120 degrees
