  1. Trigonometry 45° Triangle By Pythagoras x2 = 12 + 12 x2 = 2 x = √2 Let the leg = s Hypotenuse = s√2

  2. x= √2 x 2√2 h = 9√2 x= 4

  3. 6= x . √2 x = 6/√2 x = 6√2/2 x= 3√2

  4. 30°,60° Triangle By Pythagoras 30 22 = 12 + x2 √3 x2 = 3 x = √3 60 1 2

  5. 30 30 60 60 Let the short leg = s Hypotenuse = 2s Long Leg = s√3

  6. Hypotenuse = 2s f = 10√3/3
