Question

Two forces with magnitudes of 90 and 50 pounds act on an object at angles of 30° and 160° respectively. Find the direction and magnitude of these forces. Round to two decimal places in all intermediate steps and in your final answer.

Answer 1

I have to go but you need to use trig functions, sin and cos to break the magnitudes in to coordinates points. Then find direction, by using tan(x points/y points), and magnitude by sqrt((x2-x1)^2+(y2-y1)^2)

Answer 2

Thank you, but that is still confusing to me.
