On the vector diagram below, you are given values for the y vector
and the x vector and will solve for
. When the side opposite and
the side adjacent are given, use the TANGENT function.
NOTE: These vectors are in the IV quadrant and are treated in the
same manner as vectors in the first quadrant. In both
quadrants, the angle is the angle between the x vector
and the r vector; and the y vector is the side opposite.
Solve for
