Hi guys !

I really need help answering and seeing if I answered this question correct.

A 12-foot ladder is leaning across a fence and is touching a higher wall located 3 feet behind the fence. The ladder makes an angle of 60 degrees with the ground. Find the distance from the base of the ladder to the bottom of the fence.

The distance from the base of the ladder to the bottom of the fence is going to be

12 * √3 = 12√3

Hi;

That is not possible. You have the base of the triangle longer than the hypotenuse which is always the longest side of a right triangle.

Of course that result can be rigorously obtained, but who cares?

hi zee-f

This is the diagram I'm getting.

ladder = AD

fence = BE

wall = DE

OK so I am going to say 12 is the hypotenuse so to get the short side I divide 12 by 2 sense the hypotenuse is the short leg * 2 and I get 6 and the long leg is going to be 6* √3 = 6√3

and to get the distance from the base of the ladder to the bottom of the fence 6 - 3 = 3

So 3ft is the answer

Hi;

I hope that you are drawing a diagram whenever one of these geometry problems come up.

Of course that result can be rigorously obtained, but who cares?
