Question

What is the measure of angle B to the nearest degree?

Answer 1

looks like: \[{\large \cos(m \angle B)=\frac45}=0.8\]

so, \[m \angle B=\cos^{-1}\left(0.8 \right)\]

Answer 2

do you get 37 degrees?

Answer 3

Oh okay so if I wanted to find angle C would I solve it like this:
\[\sin^{-1} (0.8)\] which gives me 53 degrees ?
