We know the hypotenuse and are trying to find the value of \(y\), which is the adjacent. From SOH CAH TOA, we see that we need to use the cosine ration. \(\cos (x^\circ ) = \frac{{adjacent}}{{ ...

Footage of John W North High School math teacher Candice Reed wearing feathered headgear while chanting 'SOH CAH TOA' -a mnemonic for remembering the definitions of the trigonometric functions ...

As the numbers are known on the opposite and the hypotenuse, then we look for the ratio which uses both these sides (SOH CAH TOA). That ratio is the sine ratio. \(\sin (x^\circ ) = \frac{{opposite}}{{ ...
