Hi. I have the triangle PQR pq=17cm , qr=15cm and pr=8cm

I need to write down the values of sinQ,cos Q and tan Q. I know the soh,cah,toa rules but not sure how to apply them. Thank you.

Also i need to sketch curves such as y=sin x for 0degrees <and equal to x <and equal to 360degrees. then solve the equation sin x=0.5 for 0degree <and equa to x <and equal to 360 degree then illustrate these on the sketch.

I have only just started this subject and this is a beginner exercise before we begin the main lessons into it, so i would be grateful for any guidence you can give.

Thank you
