Question

What are x and y ?? Enter the answer in the box

Answer 1

Answer:

x = 10

y = 11

Step-by-step explanation:

angle C is a right angle because AC = BC, so it is 90 degrees, meaning that 9x = 90. 90 divided by 9 is 10, so x = 10.

angle A = angle B, because AC = BC, so A and B are congruent. angle A measures 72 degrees, so angle B measures (8y-16) = 72.

(8y-16) = 72

    +16   +16

      8y = 88

divide by 8 on both sides

        y = 11
