see below

Explanation:

the polar coordinate of the position vector is $(r = 7, θ = \frac{5 π}{12})$ $(r=7,theta=(5pi)/12)$
The vector may be represented as $(r cos θ ˆ i + r sin θ ˆ j)$ $(rcosthetahati+rsinthetahatj)$
= $(7 \cdot cos (5 \frac{π}{12}) ˆ i + 7 \cdot sin (5 \frac{π}{12}))$ $(7*cos(5pi/12)hati+7*sin(5pi/12))$
