What is altitude?
== == Science Major: Altitude is height above mean sea level (MSL) or true altitude, which means in reference to what sea level is on the ground, or height above ground level (AGL), which is also called absolute altitude, which means height above the ground with no reference to the ground's height above sea level. In example, if the sea level in a certain place is 100 feet and you are 250 feet above the ground, your altitude above sea level would be 350 feet, and your altitude above ground level would be 250 feet.

A 15feet ladder leaning against a bulding touches the wall 12 feet above the ground. How far from the building is the bottom of the ladder?
This is a standard right triangle problem. The formula for solving the parameter of a triangle is a^2 + b^2 = c^2 Also known as the Pythagorean theorem. So, in this problem, the ladder is the hypotenuse, that is to say side c of the triangle. The height of the house is 12 or b in this example. Finally, the distance from the house, is the unknown distance a . Applying this knowledge gives us a^2 + 12^2 = 15^2 Simplified to a^2 + 144 = 225 225 - 144 = 81 So now you have a^2 = 81. Taking the square root of each side of the equation, we're left with: a = 9 So, the ladder is nine feet away from the house at the bottom of the ladder.
Can a roofer who wants to repair your roof that is 28 foot above the ground level use a 28 feet ladder?
No. since the ladder must be on an angle it must have room so that the length of the ladder is equal to the 282 + (distance between bottom of ladder and house)2.

How important is a ladder in a swimming pool?
Ladder's are very important in a swimming pool. If you don't have a ladder, people can get hurt. If there is an emergency and someone needs help, it would take a while for the person to get help.

If A ladder leaning against a wall makes a 60 angle with the ground the base of the ladder is 3 m from the building how high above the ground is the top of the ladder?
This answer uses trigonometry to avoid a lot of work:tangent = opposite/adjacent and tangent*adjacent (base of ladder from the building) = opposite (height of ladder above ground)So: tangent 60 degrees*3 = 5.196152423Therefore: Top of the ladder above ground = 5.2 meters correct to one decimal place.More laborious methodThe right triangle formed by the wall, ground and ladder has sides in the ratio of 1::2::sq-rt-of-3. The shortest side is the one opposite the 30 degree angle, i.e., the given distance from wall to base of the ladder--3 m.The length of the ladder represents the hypotenuse of the triangle, and is twice as long, hence 6 m.And the height of the ladder's top from the ground is proportional to the third side whose length is sq-rt-3 times that of the shortest side. Sq-rt-3 is about 1.732, so height of the ladder's top at the wall is about 5.20 m, or 520 cm.

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.
