Answer:
w=58 degrees
Explanation:
The sum of all angles in a triangle should add up to 180 [ its a fact]
and the square-like shape inside the triangle represents the fact that that angle is 90 degrees.
So, we can make an equation
32+90+w=180
122+w=180 [if u add 32+90, u'll get 122]
w=180-122 [subtract 122 from both sides to isolate "w"]
w=58
