Tony calculates that 3 cubic metres of concrete is enough for the path. He decides to use a concrete mix which has: cement = 1 part sand = 2 parts gravel = 3 parts How many cubic metres of gravel does Tony need?

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°

30,40,50 is correct answer

answer: (x+2) (x+3) are the binomials for your question : )
