Suppose the cities start out with initial populations of 90,000, 90,000, and 100,000, respectively. We will denote this with the vector x(0) = 2 4 9 9 10 3 5. Write x(0) as a linear combination of v1, v2 and v3. (Recall that this simply requires solving a system of the form Ay = x(0), where the columns of A are the three eigenvectors). (c)

apex answer

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.
