Question

In a triangle ABC if angleA is 30 and AB=AC
find angleB and angleC​

Answer 1

Answer:

Ab=ac so given triangle is isosceles triangle.

So,angle b=angle c

Here angle A=30degree

Angle a +angle b+angle c=180degree.

30+angle b+angle c=180degree.

So,angle b+angle c=180-30=150

So,angle b=angle c=150/2=75degree.

Answer 2

Answer:

Ab=ac so given triangle is isosceles triangle.

So,angle b=angle c

Here angle A=30degree

Angle a +angle b+angle c=180degree.

30+angle b+angle c=180degree.

So,angle b+angle c=180-30=150

So,angle b=angle c=150/2=75degree.
