In trigonometry we use something called “SOH CAH TOA” which stands for Sine, Cosine, and Tangent. SOH CAH TOA also let’s you know what  sides you are going to use for that particular function. To find the missing hypotenuse you must follow these five simple steps.

1.) Draw and Label ( find the opp,adj and hyp) the triangle

2.) Now you will have to use the COSsine since you have the opp but not the hyp. COSsine makes up Opp over Hyp.

3.) Write it into an equation which would look like (Sin = pie /35)

4.) You then use that equation in your calculator.

To find a missing angel you start by labelling the triangle

1.) Label the triangle

2.) Since you have the opposite and the adjacent but no angle you will use tan to find the angle.

3.) The equation you will write and put it into your calculator. (ta(x)=20/5)

4.) To find the angle you have to make tan a negative (tan-1=20/5)

5.) You then put that into your calculator.
