Question

In △PQR, what is the length of LINEqr?

Answer 1

Because the angles P and R are the same, =45, then the lengths of PQ = QR.
Then, you can use the equation
\[C^2 = A^2 + B^2\]
\[PR^2 = PQ^2 + QR^2\]

Answer 2

thank you! I love you guys.

Answer 3

Can you solve that ok?

Answer 4

As long as, when you use that equation, the C is always the hypotenuse, the one across from the right angle.

Answer 5

Yep! ty :)

Answer 6

yw

Answer 7

I don't think I did it correctly because my answer didn't come up to what the choices are z_z

Answer 8

let's call the sides x
\[56^2 = x^2+x^2 = 2x^2\]
\[56^2 = 2x^2\]
did you get this when you did it?

Answer 9

yeah. It cant be simplified can it?

Answer 10

or is it 56 with a square root symbol over 2?
