A fireman is heading towards a forest fire and needs to know how far away the fire is. The person in the fire tower can determin

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:

$d=3.82 miles$
