during a marathon, amy was in second place and was told that the leader was 100 meters ahead of her and that the closest runner behind her was 75 meters back. on a number line, let’s say amy’s position is at 0, and the leader’s position is on the positive side of 0.

which number sentence correctly compares the distance between amy and the runner behind her to the distance between amy and the leader?
a. |-75| < |-100|
b. |-75| < |100|
c. |75| = |-100|
d. |-75| > |100|

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.
