Polar coordinates (r, φ)

We have the point

Substitute:

How do you evaluate: To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
The answer is C. 60. If you add 14+19+16+11 it equals 60.
