x + 80 = 2x + 10 (exterior angle property)

2x -x = 80 -10

x = 70

Answer:

the answer is 70.

Explanation:

Since x and 80 are non-adjacent co-interior angles with respect to ( 2x +10 )

So,

x + 80 = 2x + 10 ( sum of two non-adjacent co-interior angles is equal to the exterior angle of that triangle )

=> 80 - 10 = 2x - x *( switching sides of x and 10 )

=> 70 = x

So, the value of x is 70
