Question

In triangle ABC, AB = 3cm; AC = 3cm A = 50° and B=?​

Answer 1

Triangle ABC is an isosceles triangle as two sides are equal. So angles opposite to equal sides of an isosceles triangle are equal.

So angle B = angle C

Angle A = 50

By angle sum property

A + B + C = 180

50 + B + B = 180

2B = 180 - 50

2B = 130

B = 130 / 2

B = 65

Answer 2

Answer:

angle B = 65 degree

Step-by-step explanation:

using property of isosceles triangle we know angle B = angle C

then we use angle sum property of triangle that's all the angles in strangle add up to 180 degree
