Homework Statement
Find the angle between the forces given the magnitude of their resultant. (Hint: write the force one as as a vector in the direction of the positive x-axis and force two as a vector at an angle θ with the positive x-axis.)
Force 1: 45 pounds
Force 2: 60 pounds
Resultant Force: 90 lbs
Homework Equations
The Attempt at a Solution
Well, writing force one as a vector in the direction of the positive x-axis would make the first vector be <45,0>
Then I know that when adding the first and second vectors the magnitude of the resulting vector must be 90 and the magnitude of the second vector must be 60.
I don't know how to find the coordinates of the second vector such that it will have a magnitude of 60, and when added to the first will result in a vector with a magnitude of 90.
Can someone point me in the right direction.
