# What is an angle to the horizontal?

## What is an angle to the horizontal?

Definition of Horizontal Angle: a) An angle between any two points within the same horizontal plane. Definition of Horizontal: a) parallel to the plane of the horizon; level; flat. b) at right angles to the vertical; parallel to level ground.

## What does 40 degrees to the vertical mean?

​Using Vertical Angles Vertical angles are always congruent – they always have the same angle measure. If one angle is 40 degrees, the vertical angle across from it will also be 40 degrees.

What does degrees below the horizontal mean?

If the core is thrown at an angle below the horizontal, the vertical component of the velocity is negative downward toward the ground. Angles are measured using the horizontal line as the reference, so something which is thrown horizontally has an angle of zero degrees. Reply. Oct 23, 2014.

### At what angle to the horizontal should a ball be thrown so that its range?

Given RT2=5,Hence,5=5cotθ or θ=45∘.

### Why is 45 the best launch angle?

As ball speed increases, so does the drag force and the lower is the required launch angle. A launch at 45 degrees would allow the ball to remain in the air for a longer time, but it would then be launched at a lower horizontal speed at the start and it would slow down more because of the longer flight time.

Why is 45 degrees the maximum range?

The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 degrees and, therefore, θ = 45 degrees. A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.

#### What is the complement angle to 30?

60°
Each angle among the complementary angles is called the “complement” of the other angle. Here, 60° is the complement of 30°.

#### Is a vertical angle 360?

Vertical angles are formed by two intersecting lines. Both pairs of vertical angles sum up to 360 degrees.

What does 40 degrees from the horizontal mean?

Become a Study.com member to unlock this answer! 40 degrees below the horizontal means the depression from a plane of reference to an angle of 40 degrees.

## What position is horizontal?

The opposite of vertical, something horizontal is arranged sideways, like a person lying down. When you sleep (unless you’re a horse), your body is horizontal: horizontal things are parallel to the ground or running in the same direction as the horizon. If you stack books horizontally, then they’re on their side.

## At what inclination Should a player throw the ball from the horizontal so that the ball travels the maximum distance?

45 degrees
A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.

At what angle with horizontal should a ball be thrown so that the range R is related to the time of flight as R 57²?

In the case of a projectile the range R is related to the time of flight T as R=5T2. If g=10 ms−2 the angle of projection is 45o.
