(1)x+y=11 given
(2)x-y=5 given
x=5+y equality property of addition (add y to both sides of (2)
5+y+y=11 sub previous result in to (1)
2y=6 algebra and simplificatiuon
y=3 division property of equality (divide both sides by 2)
x=8 again sub previous into (1)

DOES THE ANSWER HELP YOU?
Answer:
Option D: 66 degrees
Step-by-step explanation:
Interior angles of a triangle add up to 180 degrees.
Thus, 90+24+x=180 would be the equation you make to solve:
90+24+x=180
114+x=180
x=66
So <x=66 degrees
