Solve for the value of y.

y = 5

Step-by-step explanation:

All angles must add up to 90° as you can see the right angle symbol, this means:

51 + 9y - 6 = 90

51 - 6 + 9y = 90

45 + 9y = 90

Subtract 45 from both sides of the equation to isolate the 9y:

45 + 9y - 45 = 90 - 45

9y = 45

Divide both sides by 9:

y = 5
