Question

in triangle abc if ab is equal to AC angle b is equal to 50 degree then find the angle​

Answer 1

Given that AB=AC

and ∠B=50

If adjacent sides are equal, then the angles opposite to equal sides are also equal.

by this ∠C=50°

Angle sum property ∠A+∠B+∠C =180°

by calculation

50+50+x=180. let angle A is x

x=80°

Therefore ∠A=80°
