What composition of rigid motions maps STR to MNP? A. T<-7,0>° Ry = 2
B. T<3,4>°R(90, T)
C. Rx = -5°T<-7,3>
D. Ry=3°T<-7,-1>
please help

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.

thats not a system of equations, that is a solution

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
