Answer:
4[tex]\sqrt{4}[/tex]
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[tex]\sqrt{2}[/tex]
one of the sides that has angle measure 45 is given as 4[tex]\sqrt{2}[/tex]
to find the length of BC we we need to multiply 4[tex]\sqrt{2}[/tex] with [tex]\sqrt{2}[/tex]
4[tex]\sqrt{2}[/tex] *[tex]\sqrt{2}[/tex] = 4[tex]\sqrt{4}[/tex]
