Show that PR = 10 sin 50 degrees/sin 15 degrees and PV = 10 sin 79 degrees/sin 32 degrees.
When I drew the diagram, I found out that angles 50 degrees and 79 degrees were outside the triangles. So i was just wondering how the sine rule could be applied to show the above question. All I could get was PR = 10 sin 130 degrees/sin 15 degrees and PV = 10 sin 101 degrees/ sin 32 degrees.
Please help!
