Fist at arms length = ~ 10 arc degrees
Thumb at arms length = ~ 2 arc degrees
Little finger ~ 1 arc degree

Is it true The better you can estimate an angle the better you can estimate a length?
It depends on you thinking ability
How can you calculate height of a pyramid by measuring the length of its shadow?
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
Application of relation between arc of length and central angle?
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
How would you find the distance between thes bases if the right angle is the length of about 127.3 h?
a right angle or any other angle does not have a length. your question cannot be answered.
How do you find the dot product ab of two vectors if you know their lengths and the angle between them?
<ab> = |a|*|b|*cos(x) where |a| is the length of the vector a, |b| is the length of the vector b, and x is the angle between them.

Does a angle have infinite length?
An angle has no length at all. The angle is just the amount of opening between the two lines where they meet. The length of the angle's sides is completely irrelevant, and has no effect at all on the measure of the angle. They can be any length from almost zero to infinite, and they don't even have to both be the same length. It just doesn't matter. None of that changes the measure of the angle.
When you say Tangent of 30 equals -6.40 does the -6.40 represent the length or angle of something else?
In a right triangle, the tangent of an angle other than the right angle is the ratio of the length of the side opposite the angle over the length of the side adjacent to the angle (the side between the angle and the right angle).

<ab> = |a|*|b|*cos(x) where |a| is the length of the vector a, |b| is the length of the vector b, and x is the angle between them.
The angle between two vector force of magnitude?
using the "dot product" formula, you can find the angle. where |a| denotes the length (magnitude) of a. More generally, if b is another vector : where |a| and |b| denote the length of a and b and θis the angle between them. Thus, given two vectors, the angle between them can be found by rearranging the above formula: : :
What is the difference between an arc and an angle?
An angle is measurement use to tell the distance between two lines that are concurrent at a point. An arc is the length of a curve drawn with a unchanging distance (radius length) around a point..
What is the relation between the arc length and pi?
arc length/2pi*r=measure of central angle/360
How do you find the angle of sector when arc length isn't given?
By using a protractor and finding the angle between the two radii
Can you find the 2 sides of a triangle if you only know the length of the hypotenuse and the angle between the hypotenuse and the base line?
Yes. If c is the length of the hypotenuse, and alpha is the angle between the hypotenuse and the base. If we say a is the length of the side opposite angle alpha and b is the length of the adjacent side, then the lengths a and b are as follows: a=h*sin(alpha) b=h*cos(alpha)
