Question

Solve for BC: Enter your answer in the box.

Answer 1

4
`√(4)`

Explanation:

This is an isosceles and right triangle at the same time

In fact, this triangle is called 45-45-90 special right triangle and the side lengths for this special triangle is as follows:

The sides that see the angle with measure 45 is represented with x

and

The side that sees the angle with measure 90 is represented with x
`√(2)`

one of the sides that has angle measure 45 is given as 4
`√(2)`

to find the length of BC we we need to multiply 4
`√(2)` with
`√(2)`

4
`√(2)` *
`√(2)` = 4
`√(4)`
