Answer:
31,500
Step-by-step explanation:
Multiply the population density by area to get the total population in an area
Density = 15 per km²
Area = 1500 x 1.4 = 2100 km²
Population in 2100 km² = 15 x 2100 = 31,500
Step-by-step explanation:
I will call the angle A.
we need to use cos, sine, and tangent here
cosine= adjacent over hypotenuse
sine = opposite over hypotenuse
tangent = opposite over adjacent
the angle A has x as the hypotenuse
and y is adjacent to the angle
cosine will be used
cos(A)= adjacent/hypotenuse
cos(A)= 5/x
get x alone by using opposite signs
x and 5 are dividing. the opposite of division is multiplication , but in order to cancel 5 from the right side i need to multiply the reciprocal. 5 is on top, needs to be on bottom to cancel out
cos(A)*(1/5)= 5*(1/5x)
cos(A)/5=(1/x)
flip both sides to get x on top
(5/cos(A))=x
use calculator
and make sue it is in degrees
x=5.8 cm
2. Is 30 3. Is 90 and 1. Is 70
C. Y=12
There’s no x variable
