Question

What is the value for each variable?

Answer 1

As it is a 45-45-90 triangle, the sides have lengths a : a : a*sqrt(2)
Because you know that a * sqrt(2) = 15sqrt(2), you can work out x and y.

Answer 2

Have you set a = 15? After this it is very easy...

Answer 3

a = 15? I haven't really done this before.

Answer 4

Can you show me each step?

Answer 5

Because a=15, this is also the length of the to equal sides.
So: y=15 and x=15. THere is nothing more to be done!

Answer 6

Ahh okay. Thank you.

Answer 7

YW!
