Question

triangle ABC in which angle A =90 and ab = ac find the other angles

Answer 1

As angle A=90
ab=ac
Angle B=C
In a triangle
All angles=180
Therefore
180-90=2B
90=2B
B=90/2
B=45
THEREFORE
Other angles = 45

Answer 2

∆ABC , A=90°
AB=AC
Sides are equal so, the angles are also equal
then,
90°+x+x=180°
90+2x=180
2x=180-90
2x=90
x=90/2
x=45°
then , angle A&B are 45°
