help with hard trig question: (1 Viewer)

[Najji]

I just realised that my 2nd question was different from the solution. Can someone post the working out? I just want to see where I may have made a mistake.

First draw a right angle triangle with 15.5 minutes, convert into radians = 0.004508767
use tan, tan 0.004508767 x 149000000 = 671810.8703
67810.8703 x 2 = 1343621.741 or 1343622 1 dp

Sorry never realized it was a taboo to reply to a 5 year old thread, I did it just in case someone else like me was searching for an answer, although that wasn't my question, it could be someone else's.
