Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
![### Geometry Problem: Finding the Length of \( CT \)
**Problem Statement:**
What is the length of \( CT \)? Round your answer to 1 decimal place.
**Diagram Description:**
- The diagram is a circle with center \( C \).
- Point \( A \) is on the circumference of the circle.
- Line segment \( CA \) is a radius of the circle and has a length of 7 cm.
- Angle \( \angle ACT \) measures 66 degrees.
- Line segment \( CT \) is a chord of the circle from point \( C \) to another point \( T \) on the circumference.
**Given Data:**
- Radius \( CA \) = 7 cm
- Angle \( \angle ACT \) = 66 degrees
Insert the calculated length in the provided box:
\[ CT = \boxed{} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc32fdead-cf8a-44ab-a7f8-9f10e201d4c1%2F494d6f1d-36b1-485b-9c0b-e7a0c38e9e5f%2F5tqdijf_processed.jpeg&w=3840&q=75)
