A 38 ft long ladder is leaning against an embankment inclined at 60 deg. to the horizontal. If the bottom of the ladder is 15 ft from the embankment, what is the distance from the top of the ladder down to the embankment to the ground?

Answer 1

Apply the Pythagorean theorem, a^2 + b^2 = c^2

15^2 + x^2 = 38^2

Solve for x.
