Using Pythagoras' theorem it is 20 feet

Then an angle of 58 degrees will be at the bottom of the ladder. Use trigonometry and the sine ratio: sin = opp/hyp and hyp = opp/sin hyp = 20/sin(58) = 23.58356807 length of ladder = 24 feet to the nearest foot

Using Pythagoras' theorem the the foot of the ladder should be 12 feet away from the base of the building.

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.

You should normally have three rungs(steps) past the surface you are climbing to from the ladder. They are a foot apart on most ladders so 15 feet would be close. Add a foot since you have to angle the ladder appropriately(scope) so 16 feet or longer is safe. A 20 foot extension ladder would be a good choice.

Hypotenuse = 20/sin580 = 23.58356807 Length of ladder: rounded to 23.584 feet

Unfortunately, Home Depot do not offer a 35ft extendable ladder. However they do stock a 20 or 40ft extendable ladder. The price of a 35 foot extendable ladder from Amazon is $514.
