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

## 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 1 ^{o}**

**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} **
