HOW DO I SOLVE THIS PLEASE HELP

Answer 1

• 18 units

Explanation:

Use the property of 45°x45°x90° and 30°x60°x90° right triangles.

Ratio of sides:

• 45°x45°x90° triangle 1 : 1 : √2
• 30°x60°x90° triangle 1 : √3 : 2

Find the longer leg of the second triangle:

• 6√6*√3 = 6√18 = 6*3√2 = 18√2

Find the value of x, of the first triangle:

• x = 18√2/√2 = 18
