If angle PQR is a right angle, and the line segment QS is perpendicular to line PR, can we infer that angles PQS and SQR are 45 degrees each (i.e. cut in half by line QS)? Further, if angle PQS is 45 degrees, than angle QPR, must be 45 degrees (since we already know that angle QPS is 90 degrees). Th...

I am able to come up with 4L+6, but I am having a difficult time understanding why we need to add 2 to the multiple of 4? Why aren't we adding 6 to the multiple of 4 (4L +6)? I thought the answer should be 58 (52+6), but that is not an answer choice. Can someone please explain how to get from 4L+6 t...
