Question

PLEASEEEEEEE HELP ME ASAPPPPP
Solve for x and y

Answer 1

x = 9 , y = 9
`√(2)`

Explanation:

the triangle is a 90- 45- 45 , isosceles right triangle, with congruent legs

then x = 9

using Pythagoras' identity in the right triangle

y² = 9² + 9² = 81 + 81 = 162 ( take square root of both sides )

y =
`√(162)` =
`√(81(2))` =
`√(81)` ×
`√(2)` = 9
`√(2)`

Answer 2

x = 9

y = 9√2

Explanation:

We can use the properties of an isosceles right triangle (45-45-90) to solve for x and y.

The legs of an isosceles triangle are congruent, so x = 9.

The hypotenuse of an isosceles right triangle is equal to one of the legs multiplied by the square root of 2. Therefore,

y = 9 · √2 = 9√2
