Answer:

82050 people/mi^2

Step-by-step explanation:

The population of the US is 328.2 million people and the area of the US is 4000 mi^2 as given. The population density is found by (population)/(area), so we input our values in:

Population density = 328, 200, 000/4000 = 82050 people/mi^2

I hope this helps! :)

Find X and Y using the image.

r-ruslan [8.4K]

Answer:

x = 59°

y = 130°

Step-by-step explanation:

Find x:

Recall: the measure of an inscribed angle = ½(measure of intercepted arc), based in the inscribed angles theorem

Therefore,

x = ½(118°)

x = 59°

Find y:

y = 2(180 - (56 + x)) => inscribed angles theorem

Plug in the value of x

y = 2(180 - (56 + 59))

y = 2(180 - 115)

y = 2(65)

y = 130°

Please help trigonometry

lbvjy [14]

Answer:

= 59.36

Step-by-step explanation:

S = 207

so, tan(16) = H/S

tan(16°) = 0.28674539

so H = tan(16) * S = 0.28674539 * 207 = 59.35629573

so the tree high = 59.36 foot
