Triangles
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

Re: Triangles
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.
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Re: Triangles
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.
