<u>Circle Theorem vocabulary</u>
- Chord: A straight line joining two points on the circle.
- Inscribed angle: The angle formed when two chords meet at one point on a circle.
- Intercepted arc: The arc that is between the endpoints of the chords that form the inscribed angle.
<u>Inscribed Angle Theorem</u>
The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.
Therefore:

Answer:
x² + y² = 49
Step-by-step explanation:
The equation for a circle is: x² + y² = r²
here, we know our circle's radius (r) to be 7
So, the equation for our circle is: {replace "r" with value}
x² + y² = 7²
which can be simplified to:
x² + y² = 49
hope this helps!! have a lovely day :)
