Jason is pulling a box across the room. He is pulling with a force of 15 newtons and his arm is making a 37 angle with the horizontal, if the box weighs 8 newtons what is the net force on the box in the vertical direction? Treat up as the positive direction, and down as the negative direction.

im sorry for taking These points. But I need them becauseI need help with my homework

thank you very muc

Step-by-step explanation:

where is the figure

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
