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.

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
A 12-foot extension ladder, when fully extended, reaches a maximum height of approximately 12 feet. However, the actual reach can be affected by the angle at which the ladder is placed against a wall or surface. Generally, to ensure safety and stability, it is recommended to set the ladder at a proper angle, which might reduce the vertical reach slightly.
To find how far the base of the ladder is from the building, we can use the properties of a right triangle. With a 45-degree angle, the height at which the ladder touches the building is equal to the distance from the building to the base of the ladder. Therefore, using the Pythagorean theorem, the distance from the wall is approximately 10 feet.
23.58 feetA+no its not i just tryed it so yea get your facts right before putting them on herebut i dont even know this so srry for the ppl look for it
Hypotenuse = 20/sin580 = 23.58356807 Length of ladder: rounded to 23.584 feet
Twenty divided by the cosine of 32 gives you 23.584 ft
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

assuming the wall and ground make a 90 degree angle with one another, Pythagorean's Theorem states the ladder will go 8 feet up the wall.

Answer your self dont know
he should bud the ladder so it wouldn't be able to reach
