Which equations could be used to solve for the
unknown lengths of triangle ABC? Check all that apply.

sin(45°) = BC/9
sin(45)= 9/BC
9 tan(45) = AC
(AC)sin(45°) = BC
cos(45°) = BC/9

sin (45)= 9/BC

Step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
