Which equations could be used to solve for the
unknown lengths of ABC? Check all that apply.
sin(459) = BC
sin(459) =
9 tan(459=AC
(AC)sin(45°)=BC
cos(459) = BC

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

just get this app called photo math it should be able to do those
