An experiment finds that runners with the longest legs complete a mile run in less time. Identify the relation between leg length and time of a mile run. Select the correct answer below: Leg length and time of a mile run are positively correlated. Leg length and time of a mile run are negatively correlated. An increase in leg length causes a decrease in the time of a mile run. A decrease in the time of a mile run causes a decrease in leg length.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
