(e.g angle=a)
1) Decide which out of cos, tan or sin to use
- Look at which sides are marked and then use SOCAHTOA.
2) If for exmple you chose Sin you would now know that sina=opposite/hypotenuse
- So if your sides measured 3 and 8.2 your equation would be sina= 3/8.2
3) Rearrange this to sin-1(opposite/hypotenuse) and type into calculator
4) you have found the angle!
