wild quail Question 1:

Is it using Sine? I thought Cosine.

#

yeah it uses sine

#

you can search up the derivation, you'll see why

#

in essence, it's cause when you draw the common altitude, in relation to each of the angles of the original triangle, that altitude is the opposite side

#

hence you use sin
