Question

Find the value of x and y

Answer 1

x=90: y =43

Explanation:

Given is a triangle. In ABC, AB = AC is given. also angle C = 47 is given.

AD is angle bisector of angle A

Since two sides are equal, ABC is isosceles. We have angle C = angle B

Hence angle B = 47 degrees.

Angle A = 180-(B+C) = 180-94 = 86

So angle y = 1/2 (86) = 43

Consider triangle BAD.

We have got two angles as 47 and 43.

Hence third angle is 180-(47+43) = 90

So x=90, y = 43
