Question

PLEASE HELP
Find the value of x and y. Write your answer in simplest radical form.

Answer 1

Y=10

x=14.14

Explanation:

Because the two smaller angles are equal, it is an isosceles triangle with both legs equal in length.

so y=10

By the Pythagorean theorem, x^2=10^2+10^2

x^2=200

x=14.14
