Key things to remember today

 

We are going to need to remember that a Full angle is 360º. 

All angles that make up a circle will add up to 360º.

 

Lets look at the following problem.

 

We need to find the value of e.

 

First we need to remember how many degrees are in a circle. How many are there?

 

Good 360º.

 

Next step - we need to know what the angles that we know add up to.

 

So we know the 2 angles are 146º and 117º. So lets add them together. 

Remember to use the column method to help you.

 

146 + 117 =  263.

 

Good.

 

Final step - to work out the value of e we now need to take 263º away from the 360º we know are in the full circle to work out the missing value.

 

360 - 263 = 97

 

This must mean then that the value of e is 97º.
