Please help I need help really fast Use a determinant to find
the area of the triangle
whose vertices are
A(1,1)
B(3,7)
C(9,5)

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

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°

sorry not knowing about that

step-by-step explanation:

classify each pair of angles as alternate interior, same-side interior, or corresponding angles.
