To further justify the Cofunction. Theorem, use your calculator to find a value for the given pair of trigonometric functions. In each case, the trigonometric functions arc cofunctions of one another, and the angles arc complementary angles. Round your answers to four places past the decimal point.

To determine

**To find:**

The value of the given pair of trigonometric functions by using calculator and rounding the answer to four places past the decimal point:

**Given information:**

The given pair of trigonometric functions is co functions of one another and angles are complementary angles.

**Concept Used:**

According to co function theorem: A trigonometric function of an angle is always equal to the co function of the complement of the angle.

**Calculation:**

Here the pair of trigonometric functions is

Since the given pair of trigonometric functions are in degrees and minutes therefore we will first convert them into decimal degrees as follows;
