The length of the arc intercepted by a central angle is the ratio of the angle to 360 degrees times the circumference. From the given values above,
S = (30° / 360°) x 2 x π x (6 ft)
S = π
The angle intercepted an arc which measures π feet. The answer is letter A.

Answer:
∠B = 53°
∠C = 127°
∠D = 127°
Step-by-step explanation:
The trapezoid is isosceles, as indicated by the hash marks on sides AD and BC. This means it is symmetrical about the vertical center-line. Angles on the right will have the same measures as the symmetrical angles on the left.
So, you know immediately that ∠B = ∠A = 53°.
Because AB ║ DC, ∠A and ∠D are supplementary. That is, ...
∠D = ∠C = 180° -53°
∠D = ∠C = 127°

Answer:
<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em><em><u> </u></em></h2>
Step-by-step explanation:
<em><u>As</u></em>,
It has shown that line c cuts line b by making 90° so those lines are called <em><u>perpendicular bisectors </u></em><em><u>.</u></em>
<em><u>Hence</u></em>,
<em>Option B is the correct symbol shown for perpendicular bisector of line </em><em>c</em><em> </em><em>to line </em><em>b</em><em>.</em>
