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.

Q: 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?

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

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

A degree is a measure of rotation, a foot is a measure of distance. These two are incomparable.

are they standing striaght up?

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

Round the base angle to 70 degrees and use the sine ratio: 30*sine 70 degrees = 28.19077862 feet Height of ladder from the ground = 28 feet to 2 s.f.

he should bud the ladder so it wouldn't be able to reach

30 feet. And you don't have to round it to the nearest foot. It's exactly 30 feet.
