Question

We have a side that is opposite our angle,

and we have the hypotenuse. Which ratio
will we use?

Answer 1

Sine

Explanation:

Using the acronym SOHCAHTOA, we can see that Sine (S) should be used.

SOH represents Sine, Opposite, Hypotenuse.

Since we are only given the opposite side and hypotenuse, the sine ratio should be used, which is opposite / hypotenuse

So, sine will be used.
