Sometimes SAT questions look simple just like the picture below. But we must have a strong understanding to solve SAT questions because it doesn't need a long way to solve the questions.
From the
question we know that x + y = 900
The sum of
angles of triangle is 1800 à x + y + w = 1800
900 + w = 1800 à w = 900
900 + w = 1800 à w = 900
