-- Collect all of the information you're given ... such as the dimensions of the
circle or of additional lines drawn inside the circle or touching it, and the size
of other angles that are not missing.
-- Recall and collect the various laws, relations, and formulas you know that
relate to circles, or to whatever other shapes have been added to the drawing
you have of the circle with the missing angle.
-- Identify one or two of the mathematical or geometric operations you know
that can make the connection between the given information and the missing
angle.
hi
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
No. It's a central angle only if its vertex is at the center of the circle.
(arc length / (radius * 2 * pi)) * 360 = angle
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
It depends on what information is available.
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
You can find the angle of a triangle within a circle segment using the circle theorems.
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
Subtract the two known angles from 180 degrees will give you the missing angle
the missing angle is 93 degrees. you find that out by adding 53 and 34 and then subtracting them from 180. :)
Of what?
That's how its meant to
The answer will depend on what the shape is!
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
you cant
With only one number, you cannot - unless that one number happens to be the measure of the missing angle!
