Question

Help me please - I don’t want to be wrong before I submit!

Answer 1

y = 4
`√(2)`

Explanation:

First, I drew the triangle so that they we oriented the same.

Next, I use the pythagorean Theorem to find x.

Then, I set up a proportion to find y

Answer 2

`x^2=2^2+4^2\\x^2=4+16\\x^2=20\\\\x^2+y^2=(2+8)^2\\20+y^2=100\\y^2=80\\y=√(80)=4\sqrt5`
