Answer:
supplementary angles add up to 180°
given y=65° thus...
x+y=180°
x + 65°=180°
x=180°- 65°
x=115°
It's a little hard to tell without more information as to what you are learning, but could it be the Golden Ratio? I believe it might have been discovered in ancient Greece...

Simplify:
175=7x
Divide both sides by 7:
25=x
