Finding an unknown side of a right angled triangle 2012

  1. 1. Finding an unknown side of a right angled triangle . TAKE NOTE O TanA = A Say angle is 30oTrue Values (2 dp) Example, anytime we come across a right- angled triangle with a known angle we can find an unknown side if we are given the value of one other side.Tan 30o = 0.58 h h Tan 300 = 75 ⇒ h = 75Tan 300 ⇒ h = 75x 0.58 = 43.5m 30o 75 m
  2. 2. Now use the sane workings to find the unknown side of your right angled triangle Explain every step . Clues Find length x Find area of triangle and times by 2 Add result to area of square in middle Times by length of trench
