Find the length of side x in the simplest radical form with a rational denominator

The value of x = 1

Step-by-step explanation:

Given

To determine

x = ?

Using the trigonometric ratio

cos Ф = adjacent / hypotenuse

here

Ф = 45°

adjacent of 45° = x

hypotenuse = √2

so substituting Ф = 45°  adjacent = x and hypotenuse = √2  in the equation

cos Ф = adjacent / hypotenuse

switch sides

Multiply both sides by 2

            ∵  

Divide both sides by √2

Therefore, the value of x = 1
