Which equation can be used to solve for b? Triangle A B C is shown. Angle B C A is a right angle and angle C A B is 30 degrees.
The length of side B C is 5 centimeters, the length of B A is 10 centimeters, and the length of C A is b. tan(30o) = StartFraction 5 Over b EndFraction tan(30o) = StartFraction b Over 5 EndFraction tan(30o) = StartFraction 10 Over b EndFraction tan(30o) =
