Ben will hire a crane to the workers put the bundles of shingles on the roof. there is a limit to the weight the crane can lift at one time, but ben wants the work done as quickly as possible. explain to ben what math he can use so that the crane uses the fewest lifts possible

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

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°
