Answer:
z = 63, x = 2
Explanation:
1) z has to be equal to the opposite angle:
z = 63
2) The sum of the lower angle and the 63° angle, must add up to 180°:
(10x+97) + 63 = 180
10x + 160 = 180
10x = 20
x = 2
z is 63 and x is 2
z is a mirrored angle and to get x you subtract 63 from 180(because it's a line) and then subtract 97 and divide that answer{20} by 10 to get 2 which is x
