Question

I'm solving for the angle on a right triangle the hypotenuse is 36 and the base is 24 I don't understand how or when to use cos sin tan because for some reason my school placed me in the course before I reached the requirements to take it

Answer 1

Given

hypotenuse is 36

base is 24

Procedure

Cos function (or cosine function) in a triangle is the ratio of the adjacent side to that of the hypotenuse. The cosine function is one of the three main primary trigonometric functions and it is itself the complement of sine(co+sine).

$\begin{gathered} \cos \theta=\frac{24}{36} \\ \theta=\cos ^{-1}(\frac{24}{36}) \\ \theta=48.1 \end{gathered}$

The answer would be 48 degrees
