A worker pushes a wheelbarrow up a slope with a force of 100 pounds. The slope has an angle of 15° with the horizontal. Express the force vector F in terms of i and j, where i is the force vector of magnitude 1 pound pointing along the hoizontal component of the worker's direction, and j is the vector of magnitude 1 pound pointing upwards

i know that:
Horizontal force = 100 cos 15° = 96.6

Vertical force = 100 sin 15° = 25.9
but i need to express the F vector in terms of i and j
