Question 254189
<font face="Garamond" size="+2">

That would depend on whether or not the wall and the ground form a perfect right angle.  Based on that presumption, you can proceed one of two ways:


You have a right triangle with legs of 6 and 8, so the hypotenuse, which is the length of the ladder is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ c\ =\ \sqrt{6^2\ +\ 8^2}]


Or you could note that 6 is 2 times 3 and 8 is two times 4, so you have a right triangle with legs in the proportion 3:4 which means the hypotenuse must be in proportion 3:4:5, hence 2 times 5 is 10 which is the length of the ladder.
