Answer:
x = 63 y = 27
Step-by-step explanation:
The straight line is 180 degrees
subtract 117 from 180 to get 63
It says x+7= 90, so subtract x(63) from 90 to get 27
X=4 because you combine 2+4 and subtract -6 then divide
The first incorrect is the second step so choice B. ,bc. the exponents need assuming not multiply
