Mrs A's take on finding sides using trig

Picture
Steps to do trig:
  1. Label the sides h, o and a 
  2. Cross out the side with only one thing on it
  3. Decide whether to use SOH, CAH or TOA (ie the one that doesn't have the side that has been crossed out
  4. Draw your SOH, CAH or TOA triangle
  5. Repeat the triangle - this time with the triangle information on it
  6. Write the equation
  7. Work it out
