Question

help find this
find the exact value of side b​

Answer 1

Step-by-step explanation:

To solve this we need to know that this triangle is a isosceles triangle

So AB and BC are equal

we also know that this is a right angle triangle

so angle b is 90 degree

by using Pythagoras theorem

BC^2 + AB^2 = b^2

4^2 + 4^2 = b^2

16 + 16 = b^2

32 = b^2

b = √32
