Answer:
Step-by-step explanation:
RT × TS = PT × TQ
First convert 5,280 ft. into inches.

5280 ft. equals 63360 inches.
Then you divide that by 42

If you're rounding to the nearest step then it would take 1509 steps to run 1 mile.
Dividing by 2, we have S/2=lw+lh+wh. After that, we subtract lh from both sides to get S/2-lh=lw+wh. Next, we divide both sides by w to get (S/2)/w=l+h. Next, we divide by S/2 to get 1/w=(l+h)/(S/2). Lastly, we multiply by w and divide by (l+h)/(S/2) to get w=(S/2)/(l+h)
Hypothenuse is the longest side
You can see the X is the longest
Solution: A. X
