Question

The measure of an inscribed angle is x, and the measure of its intercepted arc

is y. Which equation describes the relationship between x and y?

Answer 1

C.
`y = 2\cdot x`

Explanation:

The measure of the inscribed angle (
`x`), in angular units, is directly proportional to the measure of the intercepted arc (
`y`), in length units:

`y \propto x`

`y = k\cdot x` (1)

Where
`k` is the proportionality ratio, in length units per angular unit.

Hence, correct answer is
`y = 2\cdot x`. (Correct answer: C)
