Answer 1

Hey Henry I'm assuming Tirayr told you about this website too.\[\sin^{-1} =5/BC\]

Answer 2

which turns out to be\[\csc \theta=BC/5\]

Answer 3

You get BC=csctheta x 5

Answer 4

and you do the same for the little triangle in the top left because the angles are equal and you get AB= 4 x sec theta

Answer 5

and then you add them to get AC

Answer 6

Yep, it was Tirayr.
