  • $\begingroup$ As a side note, you didn't have to draw that second angle. The image given in the question works correctly. $\endgroup$ – Mohammad Zuhair Khan Apr 30 at 17:29
  • $\begingroup$ Ok thanks, I completely missed the fact that I didn’t need the second subtended angle and that I could work out the angle straight from the information given. $\endgroup$ – Jamminermit Apr 30 at 17:35
