Examples to show how to use the property that the measure of a central angle is equal to the measure of its intercepted arc to find the missing measures of arcs and angles in given figures.
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
The 4 interior angles of a quadrilateral add up to 360 degrees. 360-65-90-60 = 145 degrees which is the missing angle
You can find the angle of a triangle within a circle segment using the circle theorems.

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.

With a protractor. Or measure some distance, and use trigonometry.
A protractor would be helpful
With only one number, you cannot - unless that one number happens to be the measure of the missing angle!
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.

There is no specific limitation on any one angle of an inscribed quadrilateral.
-- 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.
