Answer:
x=63, y= 27
Step-by-step explanation:
x+117 = 180 They make a straight line
Subtract 117 from each side
x+117-117 = 180-117
x = 63
x+y = 90
63+y = 90
Subtract 63 from each side
63-63 +y = 90-63
y = 27
The answer is "x = 63°, y = 27°".
x and angle 117° are supplementary angles, which means the sum of both angles are 180°. Add 63 to 117 and you get 180.
