Regard the ladder as the hypotenuse and the distance from the wall as one leg of a right angled triangle.
Then, 262 = 102 + H2 : where H is the height reached up the wall by the ladder.
H2 = 676 - 100 = 576 : H = √576 = 24

How long must a ladder be to reach to top of a 20 foot wall if the ladder and the top wall form a 32 degree angle at the top in a plus?
The ladder forms the hypotenuse (r) and the wall forms the vertical (y) of a right triangle. sin theta = y / r the angle at the bottom is (90 - 32) = 58 sin 58 = 20 / r r = 20 / sin 58 = 23.583568067241928552025478405751 feet ladder must be about (rounding) 23.6 feet long.
