Question

In an isosceles triangle ABC,AB=AC and angle A=30degrees find angle B and angle C​

Answer 1

Step-by-step explanation:

A=C(opposite angle of the equal side are also equal)

a=b=30

b=180-a+c

b=180-30+30

b=180-60

b=120

Answer 2

Answer:

Given:-

AB=AC

A=30°

To Prove: measure of angle B ang angle C

Proof:-

Let angle B and angle C be x as both are equal as angles opposite to equal sides are equal.

Therefore by triangle sum property:-

x+x+30=180

2x+30=180

2x=150

x=75

Therefore,

Angle B=75°

AngleC=75°

Therefore angle C
