3. Keeping on mind that , you obtain:

Step-by-step explanation:

We want to verify that;

We take only the expression on the left hand side and work to get the expression on the right hand side.

We cancel the common factors to get;

We now use the Pythagorean identity;

We make the subject to obtain;

as required.

The basic trigonometric identity we used is

the answer would be 44.79
