Triangle A B C is shown. Angle A C B is a right angle and angle C A B is 45 degrees. The length of hypotenuse A B is 9. Which equations could be used to solve for the unknown lengths of △ABC? Check all that apply. sin(45°) = StartFraction B C Over 9 EndFraction sin(45°) = StartFraction 9 Over B C EndFraction 9 tan(45°) = AC (AC)sin(45°) = BC cos(45°) = StartFraction B C Over 9 EndFraction
