hjlf

Answer: 3.82 miles

Step-by-step explanation:

According to the shown figure, we can imagine the scene as a <u>right triangle</u>, where the tower is located at the right angle, and the fireman and the forest fire located at each of the other two vertices.

So, since we are dealing with a right triangle we can use the Pithagorean Theorem, in order to find the distance from the fireman to the fire d, which is also the hypotenuse.

d^{2}= (2.1 miles)^{2} +(3.2 miles)^{2}

d=\sqrt{(2.1 miles)^{2} +(3.2 miles)^{2}}

Finally:

d=3.82 miles

A. doesn't work because it is increasing

B. works because your finding 85 percent since you decrease by 15 percent

C. doesn't work because you are not taking 15 percent from value of t

D. doesn't work because finging 15 percent of t and them subtracting from one won't give you the right answer

E.doesnt work because all you have to do is find 85 percent not subtract that from the original value

F.works because subtracting 15 percent from one and multiply by t would give the equation from B

So the answers are B and F
