# In Trigonometry - Using Degrees and Minutes to find a side

Updated on October 4, 2010

## Degrees and Minutes

Here we are going to use the trigonometric ratios once again.

In this hub we are going to be covering finding the value of “X” while dealing with “Degrees and Minutes”

We are used to seeing Degrees in maths on their own but each degree can be split up into smaller units which are known as minutes.

There are 60 minutes in 1o

S O/H             C A/H            T O/A

## Example 1

We will be finding the value of X to 1decimal place.

First we need to look at our diagram and establish what sides are being used, so as to work out what trigonometric ratio is required to solve this equation.

S O/H                C A/H                       T O/A

Here the marked sides are the opposite and the adjacent so we are going to be using the trigonometric ratio T O/A

## Example 2

Here we will find the value of X to 2 decimal places.

We need to look at the diagram and establish what sides are being used, so as to work out what trigonometric ratio is required to solve this equation.

S O/H             C A/H            T O/A

Here the marked sides are the opposite and the hypotenuse  so we are going to be using the trigonometric ratio  S O/H

## Example 3

Find the value of X to 1 decimal place.

Here we need to look at the diagram and establish what sides are being used, so as to work out what trigonometric ratio is required to solve this equation.

S O/H             C A/H            T O/A

Here the marked sides are the adjacent and the hypotenuse  so we are going to be using the trigonometric ratio     C A/H
