Question

Help please! What is the exterior angle?

Answer 1

The exterior angle measure is 130 degrees.

Explanation:

Use exterior angle formula

`(x + 35) + 25 = 2x - 10`

Add like terms

`x + 60=2x-10`

Simplify

`x+60=2x+-10`

Subtract 2x on both sides

`-x+60=-10`

Subtract 60 on both sides

`-x=-70`

Divide by -1

`x=70`

Plug in 70 into the equation

`2*70-10`

Solve

`130`
