# Math Help - Problems Involving triangle law

1. ## Problems Involving triangle law

Diagram shows the triangle $PQR$. $M$ is the midpoint of $QR$. $MS$ is perpendicular to $PSR$

Find the length,in cm,of $QR$

2. Draw perpendicular QT, T on PR: that's PQR's height.
Angle PQT = 32 degrees; so you can now calculate QT and PT.
Is that enough for you to wrap this up?
