The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.
X would be 180 - 90 - 35 = 55 degrees
X and 2y - 5 are complementary angles which add together to equal 90:
2y - 5 + 55 = 90
Simplify:
2y +50 = 90
Subtract 50 from both sides:
2y = 40
Divide both sides by 2:
y = 20
Answer:
y = 4
Step-by-step explanation:
Move all terms not containing y to the right side of the equation.
-y = -4
Multiply each term in −
y = −
4 by −
1
y = 4
