(15/2,15sqrt3/2)

Explanation:

In Polar coordinates a point is represented as P (r,theta)
In Cartesian form it is represented as P (x,y)
Where x=rcostheta
And y=rsintheta
:. Cartesian form of P (15,(7pi)/3) will be
x=15xxcos ((7pi)/3) =15/2
y=15xxsin ((7pi)/3) =15sqrt3/2
:. The point in Cartesian coordinate will be P (15/2,15sqrt3/2)
