Find the measure of the arc or angle indicated.

The part of the circumference of the circle is called the arc and the angle subtend by the arc on the center of the circle is called indicated angle.

The size of the arc is totally dependent on the angle subtend by that arc towards the center of the circle. The higher value of the angle the more is the length of the arc.

The formulated way to represent the length of the arc is mentioned below:

It is clear from the above formula that the parameter responsible for arc length is the angle subtend by it on the center while the radius of the circle remains constant throughout.

Specifically, the term arc is used for a portion of a circle along its circumference. The size of the arc is usually given by the size of the angle subtended by the arc at the center or the length of the arc. The angle subtended at the center is also known as the angle measure of an arc or informally the arc measure.

Step-by-step explanation:

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

70
