The hypotenuse of a right triangle is 15 cm, and the shorter leg is 9 cm. Find the length of the other leg.

A. 2 square root of 3 cm

B. 12 cm

C. Square root of 6 cm

I believe that the answer is B 12 centimeters because it doesnt ask for the square root.

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."
