Using ruler and compasses only, construct triangle PQR with QR = 6.5 cm, PQ = 8.0 cm and angle PQR =75 Measure PR and state its length, in cm.

[construction lines must be clearly shown.]

Remember that the slope of a line never changes, so you can choose whatever 2 points you want and you will always get the same slope. Calculate the rise and run (You can draw it on the graph if it helps). Theslope is 2/4, which , of course, you can simplify to ½.

Hoped this helped!
