Answer:
The measure of the complement is 30°
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to 180 degrees
Two angles are complementary if their sum is equal to 90 degrees
Let
x -----> the measure of an angle
we know that
180°-x=4(90°-x)
Solve for x
180°-x=360°-4x
4x-x=360°-180°
3x=180°
x=60°
Find the complement
90°-x=90°-60°=30°

So, we have:

Reorder



Using scientific notation
;
The value (a) must be in the following interval 
So, we have:


By comparing the above with: 


We can find the answer by dividing the world population by the area of NYC in square feet.
There is 27,878,400 sq ft in a mile because 5280^2 is that value. So that means
7400000000 people in 27,878,400 sq ft. You can divide that into sqft/person which is 0.00376 sqft/person. Now multiply that by 305. you will get 1.149 sq/person in NYC.
Hope this helps!
