Question

In the figure given below, find x and y.​

Answer 1

Step-by-step explanation:

AB = BC

so, angle A= angle C = x

now,

90 + x + x = 180

2x = 90

x = 45

angle (A + B) = y

y = 90 + 45 = 135

hope it helps you

Answer 2

Answer:

In angle ABC, AB= AC

Angle BAC= Angle BCA = x ( angles opposite to equal sides are equal)

x +x + 90= 180

2x= 180-90

x= 90/2= 45

x= 45

Angle ACD= Angle BAC+ Angle ABC ( exterior angle is equal to the sum of interior opposite Angles)

Y= 90+ 45

= 135 degrees answer
