What is safe angle of inclination of ladder?
About 15 degrees. Many, if not most, extension ladders today have a sticker on the side that shows a line that should be parallel to the ground when the ladder is at the proper safe angle.
A firefighter places a ladder against a building The ladder forms a 47 angle with the ground What is the measure of the angle between the ladder and the building?
43 degresses
Was the difference between height and slant height?
Lean a ladder against a wall. Not too steep . . . Give it a nice angle, for safe climbing. The height is the distance between the ground and the place where it hits the wall. The slant height is the length of the ladder.
How long must a ladder be to reach the top of a 20' wall if the ladder and the wall form a 32 angle at the top?
23.53
What is the minimum length of a ladder required to access a roof surface 12 feet off the ground?
You should normally have three rungs(steps) past the surface you are climbing to from the ladder. They are a foot apart on most ladders so 15 feet would be close. Add a foot since you have to angle the ladder appropriately(scope) so 16 feet or longer is safe. A 20 foot extension ladder would be a good choice.

A safety regulation states that a maximum angle of elevation for a rescue ladder is 72if a fire department's longest ladder is 110 feet what is the maximum safe rescue height?
96.6 ft

43 degresses
What do you check before using ladder?
Check that the ladder is in good condition with no broken or missing parts, that the rungs are secure, and that it is at the appropriate angle for safe use. Also ensure the area around the ladder is clear of obstacles and that the ground is level and stable.
A painter is standing at the base of a ladder that is leaning against the side of a house What angle do the ladder and the house form?
It can be any angle that is more than zero degrees and less than 90 degrees. <><><> It will be an ACUTE angle, and if the ladder is placed properly (1 ft out for each 4 ft up) the angle between wall and ladder will be ABOUT 18 degrees.
Was the difference between height and slant height?
Lean a ladder against a wall. Not too steep . . . Give it a nice angle, for safe climbing. The height is the distance between the ground and the place where it hits the wall. The slant height is the length of the ladder.
Walking up a slope is easier than climbing a ladder Why?
The ladder is set at a steeper angle
What angle is a ladder fixed at on scaffolding?
A ladder should be place at 1m form the base of the scaffold .
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
what- a ladder rests against a building at an angle as shown, with endpoints (-2,0 ) and (0,8). what is the slope of the ladder?
4
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
A ladder that leans against a building makes an angle of 49 degree with the ground and reaches a point on the building 12m above the ground Find the length of the ladder to the nearest meter?
The ladder forms a right angle with the building: the ground and the building forming the right angle and the ladder forming the hypotenuse. If the length of the ladder is L metres, then sin(49) = 12/L So L = 12/sin(49) = 15.9 = 16 metres.
