Finding an Unknown Side in a Right-Angled Triangle (VCE SSCE General Mathematics): Flashcards

Sin=Opp/Hyp, Cos=Adj/Hyp, Tan=Opp/Adj

$\frac{\text{opposite}}{\text{hypotenuse}}$

$\frac{\text{adjacent}}{\text{hypotenuse}}$

$\frac{\text{opposite}}{\text{adjacent}}$

When working with opposite side and hypotenuse

When working with adjacent side and hypotenuse

When working with opposite and adjacent sides

Multiply both sides by the denominator

Multiply by $x$, then divide by trig value
