8. Find the values of the variables. a. x = 39.6, y = 10.6
b. x = 10.6, y = 39.6
c. x= 42.4, y = 158.4
d. x 158.4, y = 42.4

x = 10.6, y = 39.6

Step-by-step explanation:

Given that,

Angle A = 75°

Angle B = 90°

Angle C = 180-(A+B)

= 15°

Now, using trigonometry,

For y, using Pythagoras theorem,

Hence, the value of x is equal to 10.6 and that of y is equal to 39.6.
