45 degrees to the horizontal will give the maximum flight time for a projectile. If a projectile was fired at 90 degrees to the horizontal, (straight upwards) the projectile will go straight upwards (ignoring the shape, form and aerodynamic properties of the projectile). Likewise if you were to fire a projectile at 0 degrees to the horizontal, the projectile would follow said course, IF gravity was not in effect; a projectile needs some form of vertical velocity to overcome gravity. Hence why 45 degrees will give you the longest distance and consequently flight time.

What angle for firing projectiles gives the longest range?
It depends on the weapon. A rifle will have a very low angle--maybe ten degrees. A mortar needs a very high angle to give a good range. And a howitzer needs about a 45 degree angle to give long range.
How do you find the hypotenuse with one angle missing?
The total of the three interior angles in a triangle is 180 degrees. if you know two of the angles, subtract them from 180 and that gives you the third angle.
What is the angle of rotation in a pentagon?
360 degrees divided by 5 (sides of a pentagon) gives you 72 degrees.
How do you draw a 450 degree angle?
For a 450 degree angle, you would subtract 360 from 450, which gives you 90 degrees. Therefore, you will draw a 90 degree angle. Explanation below: There are only 360 degrees in a circle. A 450 degree angle would go around a circle once completely, then it would stop at the 90 degree angle mark.
How do you find the measure of the second angle when it gives you only one angle measure?
You can use various properties of angles to find the measure of the second angle. For example, if you can see that the two angles form a right angle, then you know they add up to 90°, so you can subtract the known measure from 90° to find the measure of the other.

How important is rifling in gun barrels?
Very important. It's what stablises the projectiles, which gives them their accuracy and range.
What is sin y?
The Sine function (abbreviated sin) takes an angle and gives a ratio which is based on the sides of a right triangle. If you have a right triangle, and one of the angles (not the right angle) is labeled y then sin y equals the length of the side opposite of angle y divided by the length of the hypotenuse. The hypotenuse of a right triangle is the longest side, and is always opposite of the right angle.
What is the humans body's longest bone?
femur or thigh bone
What angle a projectile thrown to achieve maximum horizontal distance traveled?
A trajectory of 45 degrees elevation gives the longest horizontal travel- (not taking air drag into consideration nor any aerodynamic properties of a projectile.
In a right-angle triangle the incline side multiplied by cosine of the angle gives you?
The adjacent side or base of the triangle.
How do you find the Major arc in a circle?
You Look at the angle the problem gives you
What angle is the earth spinning at?
The angle between the orbital plane and equatorial plane of the earth (i.e., the angle of axial tilt) is about 23.4 degrees. This gives rise to the earth's seasons.
Why does japan care for shinano river?
because it is the longest and gives the most supply of water
What is the longest article of the constitution?
Artcle I, which creates and gives power to the Legislative branch (Congress).
What angle of the cannon gives the greatest linear distance?
45-48 degrees
What system gives most desirable assignments to members who have served longest in congress?
Seniority system! :)
