Answer:

A. 11

Step-by-step explanation:

Since the measure of (4x- 6) is 90°, you would first solve the equation for x

4x - 6 = 90

4x - 6 + 6 = 90 + 6

4x = 96

x = 24°

-------------------------------------------------------------------------------------

Since (4x - 6) was a right angle, (x + 6y) is also a right angle. Therefore, you would do:

x + 6y = 90

24 + 6y = 90

24 + 6y - 24 = 90 -24

6y = 66

y = 11°
