Question

What is this answer I don't understand how to figure it out

Answer 1

These are congruent angles. So they would be equal to each other. 6x=4x+50

2x=50

x=25°
:)

Answer 2

(4x+50)=6x
50=2x/:2
x=25°

checking:

4*25 + 50 = 150°  (above angle)
6*25 = 150° (under angle)

They are the same angles.
