On a plane flat surface with "up" given as +y and "right" given as +x, we add two vectors. One of them has components (4, 4). Their sum is (3,6). What is the unknown second vector and what is its angle to the x-axis? Hint: The angle is the one that has a tangent that is the ratio of its y to its x component, or a sine that is the y component divided by its length. The second vector is (-1,-2). It is about 63° down from -x. The second vector is (7,10). It is about 55° up from +x. The second vector is (1,-2). It is about 63° down from +x. The second vector is (-1,2). It is about 63° up from -x.
