Question

phi · Answer

you can use pythagorean theorem to find the length (magnitude)

shadyykatie · Answer

A^2 + B^2 = C^2
4^2 + 6^2 = C^2
16 + 36 = C^2
C^2 = 52
is that correct @phi

phi · Answer

yes.  but the length C is sqr(52)  or  2 sqr(13)

phi · Answer

do you know how to find the angle?  I would use inverse tan
tan A = opposite/adjacent

shadyykatie · Answer

To be honest i don't know how to find tan at all!

anonymous · Answer

have you learnt it at all? otherwise there might be another way to solve the Q without using trig.
