Rays PQ and QR are perpendicular. Point S lies in the interior of <PQR. if m<PQS = 4+7a and m<SQR = 9+4a, find m<PQS and m<SQR.

- so far all i've done is draw a picture because my geometry teacher said that the first thing you should do when you don't get a question is break it down and just draw a picture. but i still don't get what to do. I just need to know how to start it, please :)

< = angle

All you have to do is solve and plug in:
\(\displaystyle (4+7a)+(9+4a)=90^o~.\)
 
MandyJae, normally students are expected to complete a course in Algebra 1 before enrolling in geometry. Those algebra skills are necessary to do many of the problems in geometry (like this one!).

If you do not feel comfortable with those algebra skills, perhaps you should consider re-taking algebra before attempting geometry.
