Answer 2

in these question you want to give the value of one angle

But if i conider that it is a isoceles

then

angle AB =angle AC

then let Angle Ab be x

so

We know that AB=AC then

AC angke be also x

let consider angle BAC be y

so.

then ,

angle B+angle A+angle C= 180

angle B +x+y=180

angle B =180-x-y
