The equation we can use to find the value of x in the diagram given is: B. (5x + 30) + 5x = 90.

<h3>What are Complementary Angles?</h3>

Angles that give a sum of 90 degrees when added are referred to as complementary angles.

The angles, (5x + 30) and 5x are complementary angles, since the sum of both gives a right angle (90 degrees).

Therefore, the equation that we can use to find x in the diagram is: B. (5x + 30) + 5x = 90.

Given :

New York City has a population of 8.55 million and 300 square mile area .

Manhattan has 1.64 million and 23 square miles area .

To Find :

How much greater is the population density of Manhattan than New York City.

Solution :

Population density of New York City :

$D_{NY}=\dfrac{8.55}{300}=0.029 \ million/mile^2\\\\D_{M}=\dfrac{1.64}{23}=0.071 \ million/mile^2$

Now ,

$D_{M}-D_{NY}\\\\(0.071-0.029)=0.042\ million/miles^2$

Therefore , population density of Manhattan is $0.042\ million/miles^2$ greater than New York City .

Hence , this is the required solution .
