    it should be |dw:1365471862587:dw| Anyway ,Since this is a right angle triangle then Use Sine, Cosine or Tangent . Where Sin=opp/Hyp. Cos=adj/hyp. tan=opp/adj You got it ?

    you are calculating the coefficient of g which is an angle Since you were given the Opp and the hypo. ,Therefore you will use the sin Sin(g)=10/20= ?

    If Sin(a)=1 and you need to get the coefficient of a ,how To get a ? Type on your calculator Shift+Sin+1 and the result will be the coefficient of a . Can you follow the steps ?

    In the other Triangle Do the same Steps (sin,cos,tan) And notice that : That median cut the line to two equal parts (The same length)
