Answer:
z= 117
x= 7
Step-by-step explanation:
Since angle 63 and z are on the same axis, this creates a straight line. And a straight line = 180 degrees. So z can be found by:
180-63= 117
Then x. You can still use the 180 degrees method as well.
180= 117 + (10x-7) (subtract 117 on both sides)
63= 10x-7 (add 7 on both sides)
70= 10x (divide by 10 on each side)
7=x
