Answer 2

Answer:

45°

Step-by-step explanation:

the isosceles triangle having two equal sides with their opposite angles are also equal.

so if A=90°

then angleB must be equal to angle C.

as the angle sum in triangle is 180°.

then angles B+C=180°-90°=90°

2B=90°(as B=C)

B=90°/2=45°

angle B is 45°
