Question

An airplane flies in the path shown by the vector $\overrightarrow{CD}$ on the graph below. What is the magnitude and direction of $\overrightarrow{CD}$? (1 unit represents 1 mile)


53° east of south for 5 miles
42° south for 8 miles
26° north for 7 miles
72° south of west for 6 miles

Answer 1

Ok so do you first know how to calculate the magnitude of the given vector?

Answer 2

no

Answer 3

Ok the thing is you need to split the vector into it's x and y components. This will make it into a triangle which you can then apply the pytagorean theorem (c^2 = a^2 + b^2). So i'll draw that real quick
