According to the Question :

Triangle ABC is a right isosceles triangle.

In an isosceles triangle side opposite to equal sides are also equal.

Therefore :

180 - A = Ans/2 = AB = AC
180 - 90 = 90/2 = 45 = AB = AC

Hope you like my answer.
Please make me brianliest.

★ Given :-

AB = AC

<A = 90°

Then <ABC is an isosceles triangle

So < B = < C = x

★ Angle Sum property

< A+<B +<C = 180

${ \ 90° \ + \ x \ + \ x \ = \ 180}$

${ \ 90° \ = \ 2x \ = \ 180}$

${ \ 2x \ = \ 180 \ - \ 90}$

${ \ 2x \ = \ 90}$

${ \ x \ =}$ $\cancel\frac{90}{2}$

${ \ x \ =}$ ${ \ 45}$
