What are the correct trigonometric ratios that could be used to determine the length of LN? Check all that apply. sin(20°) = L N Over 8 cos(70°) = 8 Over L N tan(70°) = L N Over M N sin(20°) = 8 Over L N cos(70°) = L N Over 8

A, E

Step-by-step explanation:

Let's go down the list:

sin(20) = LN/8

- This is correct, as you can see, the side opposite angle M is LN and the hypotenuse is 8.

cos(70) = 8/LN

- This is not correct, cosine is adjacent/hypotenuse, but this equation gives hypotenuse/adjacent.

tan(70) = LN/MN

- This couldn't help you, because you don't know the measure of MN.

sin(20) = 8/LN

- This is not a correct ratio, 8/LN represents hypotenuse/opposite.

cos(70) = LN/8

- This is correct, as you can see, the adjacent side over the hypotenuse of angle L is equal to LN/8

Hope this helps!

step-by-step explanation:

- "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."
