Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.

Given:

A figure.

To find:

The values of x and y.

Solution:

We know that, in a right angled triangle,

Multiply both sides by 16.

And,

Multiply both sides by 16.

Therefore, the missing side lengths are and .

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
