Forrest rangers are standing in a 60 meter tall tower. They spot a fire in the distance. If the angle of depression of their line of sight is 18 degrees, then find x, the straight line distance from the rangers to the fire.

i would have to say it is c.

care to share were the trapezoid shown is ?

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

3 hours and 15 minutes

hope this : )
