Question

A right triangle has side lenghts 3,4, and 5 as shown below. Use these lenghts to find cos Y, tan Y, and sin Y. I got a picture of the right triangle

Answer 1

According to the trigonometrics they are defined as

`\sin \theta=(op)/(hyp);\cos \theta=(ad)/(hyp);\tan \theta=(op)/(ad)`

identify the opposite side, the adjacent side and the hypotenesu according to the angle Y

Replace the sides to find the trigonometrics

`\begin{gathered} \sin Y=(4)/(5) \\ \cos Y=(3)/(5) \\ \tan Y=(4)/(3) \end{gathered}`
