Question

30 POINTS! Find the values of x and y

Answer 1

Given that this is an isosceles triangle, then the lengths of the sides opposite the two 45º angles have to be the same length.

For this reason, x = 8.

And since x = 8 and there's only one answer with x=8, the first option must be the answer.

You can calculate the value of y using the Pythagorean Theorem.

`y^2 = 8^2+8^2`
which will lead you to
`y=8√(2)`.
