Answer 1

QUESTION--

In a triangle abc ab=ac a=90 then b=

ANSWER--

According to the question it is clearly mentioned that it is a right angles isosceles triangle.

Solution--

All angles sum of a triangle= 180

a+b+c=180

a=90, b=c and c=b

90+2b (because b and c are same so we can write 2b)=180

2b=180-90

2b=90

b=90/2

b=45

Ans b or c =45
