Abear was seen near a campground. searchers were dispatched to the region to find the bear. assume the bear can walk in any direction at a rate of 2 miles per hour. suppose the bear was last seen 4 hrs a go how large an area must the searchers cover?

each side has a different length.  

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
