Answer:
x=25
Step-by-step explanation:
because of vertical angles theorem you set them equal to each other
4x+50=150
subtract 50 from both sides
4x=100
devide by 4 on both sides
180 degrees is half a circle so you subtract 180 from 150 to get 30, that's for both the missing angles. Then you subtract 180 from 30 to get 150 and set 4x+50=150 then solve.
