Answer:
two sides equl means two angkes equl.
means remaining angles are equal
by angle sum property
sum of all the angkes is 180
180-90 = 90
means sum of remainning two angles should be 90 and both should be eql
it is possible only if both the angles are 45
means acutually we have done 90/2 = 45
sp angle b and angle c are 45
