Question 656789
<font face="Times New Roman" size="+2">


You have a right triangle with one of the acute angles measuring 40 degrees. You have the measure of the side adjacent to that 40 degree angle.  The cosine of an angle of a right triangle is the measure of the side adjacent divided by the measure of the hypotenuse.  The hypotenuse of the triangle is formed by the ladder and therefore the measure of the hypotenuse is the measure of the ladder.

Use your calculator to do the arithmetic.

My calculator said it, I believe it, that settles it
