if the two lengths are not touching, carefully move one of them until they are. measure the length between the outside ends of the two lengths. this makes a triangle. An angle can be calculated by using trigonometry functions on two of the lengths of a triangle. these can be simple or rather complex

What is the length of the arc formed by central angle 2x?
If the angle is 2x radians then the length of the arc is 2x*r units where the radius of curvature is r units. If you measure the angle in degrees, then the length of the arc is pi*x*r/90 units.
How many degrees does one inch equal?
There is no constant relationship between units of length and units of angle.
What is the length of an arc with a radius of 5 and the central angle is 120 degrees?
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
What is the approimate side length of a square with a diagonal of 5 units?
The side length of the square is about 3.54 units using Pythagoras' theorem for a right angle triangle
How many degrees does one one thousandth of an inch equal?
There is no constant relationship between units of length and units of angle.
What is the length of the arc formed by central angle 2x?
If the angle is 2x radians then the length of the arc is 2x*r units where the radius of curvature is r units. If you measure the angle in degrees, then the length of the arc is pi*x*r/90 units.
What is the measure of an arc on an angle that is 84 degrees?
84*r*pi/180 units of length where the radius is r units of length.
How many degrees does one inch equal?
There is no constant relationship between units of length and units of angle.
What is the hypotenuse of 8 and 15?
If the sides of right angle triangle are 8 units and 15 units then the hypotenuse will be 17 units in length.
What is the length of an arc with a radius of 5 and the central angle is 120 degrees?
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
What is the approimate side length of a square with a diagonal of 5 units?
The side length of the square is about 3.54 units using Pythagoras' theorem for a right angle triangle
How many degrees does one one thousandth of an inch equal?
There is no constant relationship between units of length and units of angle.
How much is 1 decree in 5 meters?
Degrees are units of angle measurement, while metres are units of length. The two units are therefore incompatible.
How do you find the diameter when you only have the arc measure and length?
Suppose the angle of the arc is x radians and the length of the arc is a units. Then, if the radius of the circle is r units, a = rx or r = a/x So d = 2a/x units of length.
What is the length of the triangle if it's sides are 9 and 15?
It's a right angle triangle and its length is 12 units of measurement.
What is the hypotenuse if the legs are 39 and 80?
The hypotenuse of the right angle triangle is 89 units in length
Why is the answer for arc length in units and not in square units?
Because it is still length. It is measured along a curve (arc), rather than a straight line. It can be found by multiplying the arc angle (in radians) by the radius. So a complete circle has an angle of 2*pi radians. Multiply this by the radius and you have 2*pi*radius, which is the circumference of a circle (measured in units, not square units).
