Circle O is shown. Secants C A and C E intersect at point C outside of the circle to form an angle with measure 36 degrees. Seca
1 answer:
Answer:
<h2>120°</h2>Step-by-step explanation:
The external angle <C outside the circle can be expressed in terms of length of arc AE and BD using the formula below.
<C =
Next is to make the length of arc AE the subject of the formula;
<C =
cross multiply
add BD to both sides of the equation
Given
<C = 36°
arc BD = 48°
Substitute the given parameters into the formula;
Hence mArc is 120°
