Answer:
x=9
z=73
Explanation:
Angle 107 and 8x+35 are vertical angles, so they are equal
107 = 8x+35
Subtract 35 from each side
107-35 = 8x+35
72 = 8x
Divide by 8
72/8 = 8x/8
9 =x
We also know that 107 and z are supplementary angles since they form a straight line. This means they add to 180 degrees
107+z = 180
Subtract 107 from each side
107-107+z=180-107
z =73
