Aline segment on a coordinate plane representing the distance a bicyclist is from home has a slope of . on the line segment, x represents the time, in hours, that the bicyclist has been riding and y represents the bicyclist’s distance, in miles, from home. the bicyclist began his ride at home and rides his bicycle at a constant rate. how long will it take until the bicyclist is 140 miles from home?

answer is x<

the answer is su.k.my? ? co.kc

step-by-step explanation:

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.
