Question

in triangle ABC, AB = AC and A=80• find the measure of X and Y​

Answer 1

Answer:

Given,

In ABC,

AB = AC

;<ABC = <ABC

;<ABC+ <ACB+ <BAC = 180°

;2<ABC + <80° = 180°

;<ABC = 100°/2 =50°

;<CBA = < BCA = 50°

Now,

<ABC+<X = 180°. ( L.P.A)

;<X = 180°-50° = 130°

Similarly,

<Y = 130°

;

Answer 2
