Students were asked over to answer a question at school and to indicate what is most important for them to succeed. The one which response stood out from the rest was practice. Successful people are generally not born successful; they become successful through hard work and commitment. If you tend to complete your goals, keep this in mind! the following some question and answer examples that you could actually implement to expand your knowledge and gain insight that will guide you to sustain your school studies.
Question:
What is the measure of angle COA?
140°150°160°170°
Answer:
To solve the problem we must know the concept of the Center angle theorem. The measure of the center angle ∠AOC is 160°.
What is the central angle theorem?
According to the central angle theorem, if an arc of a circle makes an angle with any point on the circumference of that circle then the measure of that angle is half the angle made by that arc at the center of the circle.
Given to us
∠ABC = 80°
As we already know the angle made by Arc AC at point B, therefore, the center angle made by ARC AC at the center will be twice of it. Therefore,
∠AOC = 2∠ABC
∠AOC = 2(80°)
∠AOC = 160°
Hence, the measure of the center angle ∠AOC is 160°.
