- 1AdjacentAdjacent is the side next to
the angle - 2HypotenuseThe hypotenuse is the longest side
(the diagonal line) - 3OppositeOpposite is the side opposite to
the angle - 4SOHSin= Opposite/Hypotenuse
This finds the adjacent side - 5CAHCos=Adjacent/Hypotenuse
This finds out the Opposite - 6TOATan=Opposite/Adjacent
This finds out the Hypotenuse - 7If the hypotenuse is 20 And the angle is 45 How do we work out the opposite?Start with: sin(45°) = Opposite/Hypotenuse
In what we know: 0.7071... = Opposite/20
Swap sides: Opposite/20= 0.7071...
Multiply both sides by 20: Opposite =0.7071... × 20
Calculate:
Opposite = 14.14 (to 2 decimals)
