Question

if ∆ABC = ∆DEF , find the value of x and y
​

Answer 1

Answer:

The Correct Answer is ∠D = y = 65 and ∠F = x = 45

Step-by-step explanation:

First, by angle sum property of triangle we will find out angle A,

60 + 45 + A = 180

115 + A = 180

A = 65

Since these triangles are congruent,

So all the corresponding angles will also be equal,

∠A = ∠D,  ∠B = ∠E, ∠C = ∠F

Therefoe,

∠D = 65 and ∠F = 45
