+x is to the right; +y is up
Vector A has a length of 3.76 cm and is at an angle of 34.5 degrees above the positive x-direction. Vector B has a length of 4.53 cm and is at an angle of 34.1 degrees above the negative x-direction.
What is the sum (resultant) of the two vectors?
Here are a few geometric methods:
To solve for the magnitude and direction of the resultant vector, apply the Cosine Law and the Sine Law to the triangle you obtain using one of the above methods.
