Question

Find the value of the variable.

Answer 1

Answer:

the value of x and y is the same which is 21.22

Answer 2

Answer:

x = 15√2 ; y= 15√2

Step-by-step explanation:

Thanks to the given informations we can say that the triangle is isosceles, so the leg are congruent x = y

For the Pythagorean theorem, we have

x^2 + x^2 = 30^2

2x^2 = 900

x^2 = 450

x = $\sqrt{2 * 3^2 * 5 ^2} = 15\sqrt{2}$
