Answer 2

Answer:

In an isosceles triangle two sides are equal

Step-by-step explanation:

Since we know that angles opposite to equal sides are equal

Therefore, angle B = Angle C

Sum of angles in a triangle = 180 degree

A+B+C = 180 degree

30+2B= 180 degree (angle B= angle C)

Angle B = 75 degree

since B=C

Therefore, B=C=75 degree
