elevation

elÂ·eÂ·vaÂ·tion / ËŒelÉ™ËˆvÄ�shÉ™n/ â€¢ n. 1. the action or fact of elevating or being elevated: her sudden elevation to the cabinet. âˆŽÂ  augmentation of or increase in the amount or level of something: âˆŽÂ  (in a Christian Mass) the raising of the consecrated elements for adoration. 2. height above a given level, esp. sea level: a network of microclimates created by sharp differences in elevation a total elevation gain of 3,995 feet. âˆŽÂ  a high place or position: most early plantation development was at the higher elevations. âˆŽÂ  the angle of something with the horizontal, esp. of a gun or of the direction of a celestial object. âˆŽÂ  Ballet the ability of a dancer to attain height in jumps. 3. a particular side of a building: a burglar alarm was prominently displayed on the front elevation. âˆŽÂ  a drawing of the front, side, or back of a house or other building: a set of plans and elevations.

Question:A landscaper is making a retaining wall to shore up the side of a hill. to ensure against collapse, the wall should make a 75 degree angle with the ground. If the wall is 25 feet, what's the height of the hill? A. 6.5 ft B. 25.9 ft C. 24.1 ft D. 93.3 ft its a bonus question off of my quiz that i cant figure out :[ the wording of the question is confusing.

Answers:The height of the wall itself is 25 feet, and it makes a 75 degree angle with the ground. This can be drawn as a right triangle with a hypotenuse of 25, and the angle at the ground with the hypotenuse of 75 degrees. The height of the wall will be the vertical side opposite the 75 degree angle. The trig ratio that describes the problem is sin 75 = x / 25. Since x has to be less than 25 (and just a little bit less, the answer is 24.1 feet ). (the hypotenuse always is the longest side).

Question:1) TRUE or FALSE: if three sides of a triangle measure 0.7cm , 2.4cm and 2.5cm, the triangle cannot be a right triangle 2) The odometer on a car lets us know when the car is running out of gas. The pointer on the odometer is 6 cm long. When the angle of elevation of the pointer is 32 , the car is low on gas. Find the height of the tip of the odometer when the car is low on gas. -5cm -32cm 3.2cm

Answers:<< TRUE or FALSE: if three sides of a triangle measure 0.7cm , 2.4cm and 2.5cm, the triangle cannot be a right triangle >> If the above is a right triangle, then it must satisfy the Pythagorean theorem, i.e., 2.5^2 = 0.7^2 + 2.4^2 6.25 = 0.49 + 5.76 6.25 = 6.25 Since the left hand side is equal to the right hand side, the dimensions satisfy the Pythagorean theorem, hence the triangle is a right triangle. << The odometer on a car lets us know when the car is running out of gas.
