A ramp 18 feet long rises to a platform that is 16 feet off the ground find X the angle of elevation of the round round your answer to the nearest 10th of a degree

The angle of elevation X = 62.7 degrees

Step-by-step explanation: Please refer to the attached picture for details.

The ramp rising from the ground is given as line XZ which is 18 feet. Also it rises 16 off the ground which is also given as line YZ. The angle of elevation of the ground, that is, angle X is the angle formed at point X where the ramp begins to rise. We shall apply the trigonometric ratio to solve for angle X, having been given two sides of the right angled triangle. The side YZ is the line facing the reference angle (opposite) while the side XZ is the line facing the right angle (hypotenuse).

SinX = opposite/hypotenuse

SinX = 16/18

SinX = 8/9

SinX = 0.8888

From your calculator or table of values,

X = 62.7339

Rounded to the nearest tenth of a degree,

X = 62.7 degrees

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

168

step-by-step explanation:

i am pretty sure that the answer is 168
