Homework Statement


S is a vector 24.3 units in magnitude and points at an angle of 54.8 degrees below the negative x-axis. T is a vector 18.8 units in magnitude and points at an angle of 37.7 degrees above the positive x axis. Find the resultant of the two vectors by resolving into rectangular components.

Sketch right triangles involving S and T and use cosine and sine to find each vector's x and y components. Then add the components.

How do I know what the other angles are aside from 90 degrees?

You can use the tangent to find them, since you know the length of the adjacent and opposite sides.

The problem statement gives one of the angles of each triangle. Did you remember that the complementary angles of a right triangle sum to 90 degrees?
