What is the equation for determining the angle measures?

Question

( 7× -9) + 4x =

Answer 1

11x - 9

Answer 2

Explain

Answer 3

To find the angle measures, you would set up the equation:

(7x - 9) + 4x = angle measure

Then, you combine like terms of x:

7x + 4x - 9 = angle measure

11x - 9 = angle measure

So the equation for determining the angle measures is 11x - 9.
