Draw PQ of length 8
Construct the two angles. Note that 105 = 60+45, 30 = 60/2. If you can construct a 45 or 60-degree angle, this will be easy. Where the line from Q intersects the line from P will be S.
Draw QS
Since PR=RS, R lies on the perpendicular bisector of QS. Construct that line segment.
Draw a circle of radius 9 with center at P. Where it intersects the perpendicular bisector of QS will be R.
google can help if you have difficulty with any of these steps.
