Question

find the value of X and Y in the following isosceles triangle.​

Answer 1

Answer:

according to ASP angle sum properties

A° + B° + C° = 180°

so 110 ° is A°

so the sum of 2 other angle r 70 °.

and it is isosceles means two angle and 2 sides r equal

so X ° = Y °

2X° = 70°

X° = 35 °

Answer 2

Answer:

Step-by-step explanation:

Suppose, <ACB = x

or, y=x

Now, <BAC + < ABC + <ACB = 180degree (Being sum of interior angle of  

                                                                                                 triangle)

or, 110 degree + x + y = 180 degree

or, 110 degree + x + x = 180 degree

or, 110 degree + 2x = 180  dregree

or, 2x = 180-110

or, 2x = 70

or, x = 70/2

or, x = 35 degree

Again,

       <ACB = x

    or, y = x

     or, y = 6o degree
