Question

Plz help me and include the steps of how you got the answer.

Answer 1

x = 17, y = 25.5

Explanation:

Since ABC is congruent to DEF, we can say that angle A = D and B = E by CPCTC

So to find x we can do:

5x + 2 = 87

5x = 85

x=17

So x is 17

Since B = E and E is 42 degrees, then B must also be 42 degrees. So 87 , 42, and 2y must add up to 180 degrees because it is a triangle.

87 + 42 + 2y = 180 degrees

129 + 2y = 180

151 = 2y

y = 25.5

So x = 17 and y = 25.5
