Question 597679
The sun deck at Francine's house is 30 feet above the beach.The slope of the stair's from the beach is 1.2. How long is the handrail for the stairs.
---------------------
Draw the picture.
You have a right triangle with height = 30 and slope = 1.2
slope = height/base = 1.2/1 
base = height/1.2
base = 30/1.2 = 25
----
hypotenuse = rail = sqrt[25^2+30^2] = 39.05 feet.
