14. MODEL TRAINS Amy is setting up two parallel train tracks so that a third track runs diagonally across the first two. To
properly place a switch, she needs the angle between the
diagonal and the top right portion of the second track to be
twice as large as the angle between the diagonal and bottom
right portion of the first track. What is the measure of the
angle between the diagonal and the top right portion of the
second track? (Lesson 3-2)

here the number -5 is all of the following except a rational number.

step-by-step explanation:

the answer is c)8

step-by-step explanaction:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

i'm not really sure how to answer that
