Answer:
x = 20
Explanation:
the two angels are congruet meaning they have the same angle
to find x you plug the two equations equal to each other and solve for x
3x + 50 = 6x - 10
subtract 3x by both sides --> 50 = 3x - 10
add 10 to boths sides --> 60 = 3x
now to get x alone divide boyh sides by 3 --> 60/3 = x
x = 20
