Question

Find the measure of the angle with the red dot. (This is NOT asking you to give the value
for x)
10x – 20

7x + 4

Answer 1

The answer is 60 degrees.

The two equations given are congruent so set them equal to each other and solve.

You get x = 8.

Plug that 8 back into one of the equations to get 60 degrees.
