Question

In triangle ABC, if AC=AB and ∠A measures 58°, find the measure of ∠B.​

Answer 1

Step-by-step explanation:

As,AC=AB,

It is an Isosceles triangle.

In an Isosceles triangle,the angles made by Equal sides are equal.

==>>A°+B°+C°=180° [Angle-Sum Property]

==>>58°+x+x=180°

==>>58°+2x=180°

==>>2x=180-58

==>>2x=122

==>>x=122/2

==>>x=61°

Therefore B°=61°
