P and q are complex numbers such that |p|=2/5x+1 , |q|=x+1 , and |p+q|=3x+2 .

On what interval must x fall?

[−5/2,0]
[−1,∞)
(−∞,−5/2]
[−1,0]

c is the final : )

$15 each

step-by-step explanation:

$45/3 children= $15 each

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.
