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.

Sagot :

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

[tex]\begin{gathered} \tan 37=\frac{9}{QR} \\ QR=\frac{9}{\tan37} \\ QR=11.9 \end{gathered}[/tex]

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

[tex]\begin{gathered} \sin 37=\frac{9}{PR} \\ PR=\frac{9}{\sin 37} \\ PR=15 \end{gathered}[/tex]

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°.
