A roller coaster moves 200ft horizontally it rises 135ft at angle of 30degrees above horizontal It travels 135ft at angle of 40degrees below horizontal What is displacement from start point to end?
420 feet at about an angle of -3 degrees.
What is the object in angle of elevation and depression?
It can be any object that is above or below the horizontal from the perspective of a viewer.
What is the angle of declination and how do you use it?
An angle of declination is relevant when an observer is at a higher altitude than the object being observed. It is the angle made by the line of sight with the horizontal. Suppose this is angle x. Then if the altitude of the observer is known to be h, then line-of-sight distance to the object is h*sin(x). The object is h*tan(x) from the point below the observer at the level of the object.Conversely, if the line-of-sight distance from the object to the observer or the horizontal distance to the point directly below the observer is known, it is possible to calculate the height of the observer.
How do you find the angle of depression?
The angle below horizontal that an observer must look to see an object that is lower than the observer. Note: The angle of depression is congruent to the angle of elevation (this assumes the object is close enough to the observer so that the horizontals for the observer and the object are effectively parallel; this would not be the case for an astronaut in orbit around the earth observing an object on the ground).
A ball is thrown with a velocity of 40 meters per second at an angle above the horizontal. If the ball attains its maximum range what was the value of the angle?
At 45 degrees. Yay! I got a proof done, check the link below, back to studying derivations for a infinite line of charge, ewww. The Related Question may answer yours. (See below left.)
What degree equals a acute?
Any angular measurement below 90 degrees is an acute angle. Any angular measurement below 90 degrees is an acute angle.
A roller coaster moves 200ft horizontally it rises 135ft at angle of 30degrees above horizontal It travels 135ft at angle of 40degrees below horizontal What is displacement from start point to end?
420 feet at about an angle of -3 degrees.
What angle is 87.177?
An angle that measures 87.177 degrees would be considered an acute angle. This is because its degrees measurement is below 90 degrees.
What is the object in angle of elevation and depression?
It can be any object that is above or below the horizontal from the perspective of a viewer.
What is the mathematical definition of angle of depression?
Angle of depression is defined as the angle between the horizontal line and the line joining the observer's line of sight to an object below the observer's eye sight. You can be on top of a building and an object is situated on the ground, and the angle between your horizontal line and the object is the angle of depression.
What is an 80 degree angle?
An 80 degree angle is an acute angle. Any angle measurement that falls below 90 is acute while anything above is obtuse.
What are Horizontal stems below the ground are called?
Those are called "runners". Rhizomes
Which angle is 128 degrees?
A 128 degree angle would be an "obtuse" angle. This is because the angle measurement exceeds 90 degrees. Anything below 90 degrees would be considered an "acute" angle.
How much does a acute angle measure?
an acute angle doesn't have an exact measurement, but it is lower than 90 degrees. So any angle below 90 degrees is an acute.
How do you show an angle of 331 degrees with a protractor?
Draw a straight horizontal line. Draw a 29-degree angle below the line. Indicate that 331 is the rest of the space.
What angle measures 160 degrees?
An angle that is 160 degrees would be an "obtuse" angle. This is because the measurement of degrees exceeds 90. Anything below 90 degrees would be an "acute" angle.
What angle measures 145 degrees?
An angle that measured 145 degrees would be considered an "obtuse" angle because its measurement exceeds 90 degrees. Anything below 90 degrees would be considered an "acute" angle.
