What else can I help you with?
A ladder is leaning against a building the distance from the building to the botton of the ladder is 7 feet the ladder is 25 feet long how high up the building is the top of the ladder?
It is: 24 feet by using Pythagoras' theorem
What is the slope of the ladder when the ladder is placed 4 ft away from the house and is 16 ft tall on the house?
The slope is 4 (no units), and the ladder is 16.492 feet long. (rounded)
Do perpendicular lines intersect at acute angles?
They can but don't have to as long as they are intersecting it doesn't matter whatt type of angles they form. * * * * * NO! The fact that they are perpendicular means that they intersect at right angles. Not an acute angle, not an obtuse angle but a right angle. That is what perpendicular is.
The foot of a ladder is placed 6 feet from a wall If the top of the ladder rests 8 feet up on the wall. how long is the ladder?
62+82=36+64=100 and the squared route of 100 is 10
What is the name of the angle whose vertex is c?
It could be called angle C, as long as that name is unambiguous.
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 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
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
A 15 metre long ladder is placed against a wall in such a way from the wall up to what height does the ladder reach the wall?
15 meters, or less, depending on the angle.
How long must a ladder be to reach the top of a 20 ft wall if the ladder and the wall form a 32 degree angle?
A ladder leaning against a 20ft wall, with an angle of 32 degrees with respect to the wall, must be 24ft long. cos(theta) = adjacent over hypotenuse cos(32) = 20 / hypotenuse hypotenuse = 20 / cos(32) hypotenuse = 23.58
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 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.
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 at the top?
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 ladder 10 ft long leaning against a wall at a 71 angle how high up the wall does the ladder reach?
10 sin71 = 10 x 0.9455 = 9.455 feet (just under 9' 5½")
What is the angle of elevation of a ladder leaning against a wall if the ladder is 2 meters long and reaches a height of 1.5 meters?
The angle of elevation of the ladder leaning against the wall is approximately 48.59 degrees.
How long a ladder is required to reach the roof?
that depends on the hieght of the building.
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
