Question

Solve for BC: Enter your answer in the box.

Answer 1

Answer:

4$\sqrt{4}$

Step-by-step 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$\sqrt{2}$

one of the sides that has angle measure 45 is given as 4$\sqrt{2}$

to find the length of BC we we need to multiply 4$\sqrt{2}$  with $\sqrt{2}$

4$\sqrt{2}$ *$\sqrt{2}$ = 4$\sqrt{4}$
