A 40 foot ladder is placed against a building the ladder forms a 75 degree angle with the ground How high up the building does the ladder reach?
115
How long must a ladder be to reach the top of a 20' wall if the ladder and the wall form a 32 degree angle at the top?
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
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.
What is a ninety degree angle in feet?
A degree is a measure of rotation, a foot is a measure of distance. These two are incomparable.
How is the 6 foot ladder higher then the 5 foot ladder?
are they standing striaght up?
How long must a ladder be to reach the top of a 20 foot wall if the ladder and the wall form a 32 degree angle?
Hypotenuse = 20/sin580 = 23.58356807 Length of ladder: rounded to 23.584 feet
How long must a ladder be to reach the top of a twenty foot wall if the ladder and the wall for a 32 degree angle?
Twenty divided by the cosine of 32 gives you 23.584 ft
How long must a ladder be to reach the top of a 20' wall if the ladder and the wall form a 32 degree angle (at the angle)?
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

Ladder stand 10 foot tall when braced against a wall the bottom of the ladder is 6 foot away from the wall how far up the wall does the ladder go?
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.

If a ladder 40 feet long is placed so as to reach a window 30 feet high. What angle does it make with the level ground and how far is its foot from the base of the building?
Answer your self dont know
A 30 foot ladder leaning against the side of a house makes a 70 degrees 5' angle with the ground how far up the side of the house does the ladder reach?
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.
Pyhtagorean Theorem A firefighter has a 22-foot ladder If he stand the bottom of the ladder 7 feet from the base of a building will the ladder be long enough to reach a window 19 feet from the groun?
he should bud the ladder so it wouldn't be able to reach
If A painter leans a 34ft ladder against a building The base of the ladder is 16ft from the building To the nearest foot how high on the building does the ladder reach?
30 feet. And you don't have to round it to the nearest foot. It's exactly 30 feet.
