The Vector A is 3cm long and points to the right. The vector B is 6cm long and makes an angle of 130 degrees with the horizontal (take 0 degrees to be to the right). The vector C= A+B. What is the lenght and direction of C?

Answer 1

A = (3,0)
B = (6 cos130,6 sin130)
now add the x- and y-components to get C.
Then convert to polar form as usual.
