First, draw a picture of the situation.
Let the length of the ladder be X.
Notice that X is the hypotenuse of a right triangle.
Notice that the side opposite of the known angle is known.
Remember that the sine of an angle is (side opposite)/(hypotenuse), so that sin46o=15'/X
solving for X gives X=20.85'

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.

What is the answer to A 15-m long ladder rests against a wall at an angle of 60 degrees with the ground How far is the foot of the ladder from the wall?
15*cos(60) = 7.5 7.5 m
A ladder leans against a wall making an angle of 73 degress with the ground The ladder's base is 1.17m away from the wall Determine the length of the ladder?
Providing that the ground is level and that the wall is straight, you have the outline of a right angled triangle with an adjacent angle of 73 degrees and an adjacent length of 1.17 metres. In order to find the length of the hypotenuse (which is the ladder itself) we use the cosine ratio: cosine = adjacent/hypotenuse Which when rearranged is: hypotenuse = adjacent/cosine hypotenuse = 1.17/cosine73 degrees = 4.001755235 So the length of the ladder is 4 metres correct to one significant figure.

Can you put a ladder to the sun and climb up?
First, you would need a ladder approximately 93 million miles long and able to withstand the massive temperatures the sun creates (the corona is around 1 million degrees, the surface is around 5,000 degrees, and the core is around 15 million degrees Fahrenheit). Even if you had this ladder, the sun has no solid surface against which to prop the ladder, and the Earth's rotation would prevent you from having the legs of the ladder on the ground while still pointing the top of the ladder at the sun. In short, the answer is "No".

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.
An 80kg man is 14 of a way up a 10m ladder that is resting against a smooth frictionless wall What is the friction force if the ladder weighs 20kg and makes an angle of 60 degrees?
170 newtons
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.
