A 15 foot ladder is leaning against a 30 foot wallthe bottom end of the ladder is 9 feet from the wallhow many feet above the ground does the ladder touch the wall?
12 feet.
If a 15foot ladder is leaning against a 30foot wallthe bottom of the ladder is 9feet from the wallhow many feet above the ground does the ladder touch the wall?
Use Pythagoras' theorem: 152-92 = 144 and the square root of 144 is 12 Answer: 12 feet
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
A ladder is leaning against a wall If the angle is between the ground and the ladder at 60 degrees and the wall is 4m how long is the ladder Give exact values?
If the angle between the ladder and the ground is 60 deg, and you know the angle between the ground and the wall is 90 deg, then you have a 30-60-90 degree triangle, which is a common triangle. You should memorize this one. The commonest sides of this right triangle are 4-5-6, with the longest side being the hypoteneuse, in this case the ladder leaning from the ground to the wall. The wall is 4m high, the base of the ladder would be 5m out from the wall, and the length of the ladder is 6m.
9.0 m ladder rests against the side of a wall the bottom of the ladder is 1.5 m from thebase wall derter the measure of the angle between the ladder and the ground to the nearest degree?
Oh honey, we've got ourselves a classic right triangle situation here. Using some good ol' trigonometry, you can find that the angle between the ladder and the ground is approximately 83 degrees. Just remember, math may not be your friend, but it's definitely not your enemy either.
