Question

Trigonometry anyone? Treat urself haha

Answer 1

AC = 4.34 cm

Explanation:

You have an angle and its opposite side. That allows you to establish a ratio in the law of sines, so use the law of sines.

`(a)/(\sin A) = (b)/(\sin B) = (c)/(\sin B)`

`(8.15~cm)/(\sin 110^\circ) = (AC)/(\sin 30^\circ)`

`AC = (8.15~cm * \sin 30^\circ)/(\sin 110^\circ)`

`AC = 4.34~cm`
