Question

im using goformative to answer my question and I already did number 7 but the rest show my answer is incorrect so I will appreciate if I can get a help from you, I will paste the image of the work.

Answer 1

To get side QR we can use the the tangent function:

`\begin{gathered} \tan 37=(9)/(QR) \\ QR=(9)/(\tan37) \\ QR=11.9 \end{gathered}`

Now, to find PR we can use the sine function:

`\begin{gathered} \sin 37=(9)/(PR) \\ PR=(9)/(\sin 37) \\ PR=15 \end{gathered}`

Finally to find the remaining angle we have to remember that the interior angles of any triangle have to add to 180, then angle P is 53°.
