The population of a city in 2005 was 36,000. by 2010, the city’s population had grown to 43,800 people.

assuming that the population of the city has grown exponentially since 2005 and continues to grow at the same rate, what will be the population in 2015? give your answer to the nearest whole number.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
