The sine theorem:
sin 𝐴 sin 𝐡 sin 𝐢
In this context, angles are denoted with capital letters (the angle vertex),
while sides β€” with small letters (side π‘Ž is opposite to the angle 𝐴).

1. 𝐴 = 77Β°, 𝐢 = 23Β°, 𝑐 = 16, find π‘Ž.


sin 𝐴

sin 77Β°

= sin 𝐢, i.e. π‘Ž = 𝑐 βˆ™ sin 𝐢 = 16 βˆ™ sin 23Β° β‰ˆ πŸ‘πŸ—. πŸ—.
sin 𝐴

2. π‘ž = 25, 𝑃 = 13Β°, 𝑄 = 70Β°, find 𝑝.


sin 𝑃

sin 13Β°

= sin 𝑄, i....

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
