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.

How far up a wall will a 10-meter ladder reach if the foot of the ladder is 5 meters away from the base of the wall?
To determine how far up the wall the ladder will reach, we can use the Pythagorean theorem. The ladder, the wall, and the ground form a right triangle where the ladder is the hypotenuse. If the ladder is 10 meters long and the foot is 5 meters away from the wall, we can calculate the height (h) as follows: ( h = \sqrt{10^2 - 5^2} = \sqrt{100 - 25} = \sqrt{75} \approx 8.66 ) meters. Therefore, the ladder will reach approximately 8.66 meters up the wall.
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 the top a wall of a 6.2 meter wall if the foot of the ladder must be 2.3 meter from wall?
To find the length of the ladder, we can use the Pythagorean theorem, where the length of the ladder is the hypotenuse. The wall height is 6.2 meters (one side), and the distance from the wall to the foot of the ladder is 2.3 meters (the other side). Using the formula ( c = \sqrt{a^2 + b^2} ), where ( a = 6.2 ) meters and ( b = 2.3 ) meters: [ c = \sqrt{(6.2)^2 + (2.3)^2} \approx \sqrt{38.44 + 5.29} \approx \sqrt{43.73} \approx 6.6 \text{ meters} ] Thus, the ladder must be approximately 6.6 meters long to reach the top of the wall.
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.
Who wrote the following saying the rung of a ladder was never meant to rest upon but only to hold ones foot long enough to enable them to put the other foot higher?
The saying, "the rung of a ladder was never meant to rest upon but only to hold one's foot long enough to enable them to put the other foot higher," is attributed to Thomas Henry Huxley. Huxley was a prominent English biologist and anthropologist in the 19th century, known for his advocacy of Darwin's theory of evolution. This metaphor emphasizes the idea of progress and the importance of striving for higher goals rather than becoming complacent.
How can I safely access the roof using a ladder extension?
To safely access the roof using a ladder extension, make sure the ladder is long enough to reach the roof and is securely placed on a stable surface. Extend the ladder at least 3 feet above the roof edge for stability. Use proper ladder safety techniques, such as maintaining three points of contact and facing the ladder while climbing. Have someone hold the ladder at the base for added stability.

13 feet
How can I safely put a ladder on a sloped roof?
To safely put a ladder on a sloped roof, use a ladder stabilizer or standoff to keep the ladder stable and prevent it from slipping. Make sure the ladder is long enough to extend at least 3 feet above the roof edge for proper support. Position the ladder at the correct angle, with the base of the ladder 1 foot away from the wall for every 4 feet of ladder height. Always have someone hold the ladder while you climb for added safety.
A boat has a rope ladder attached to it. The ladder goess 1 foot into the water. It starts to rain. It rains 1 inch of water per 45 mins. How long will it take until the ladder is 3 ft into the water?
The boat rises as the water rises so the ladder will always be 1 foot in the water.
A rope ladder hangs over the side of a boat The rungs are 1 foot apart and the ladder is 8 feet long?
Remember the boat rises with the tide!
