The answer is the measure of CA = 54°
An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle.
In the circle, the two lines AC and AD intersect outside the circle at the point A .
m∠CAE=1/2(m CD−m BE)
The formula for the angle between 2 secants is
1/2 (124 - 16)
= 1/2 * 108
= 54°
Therefore the measure of CA = 54°
