Answer:
a = 24°
Step-by-step explanation:
Draw a radius from to the end of the chord.
The angle in the small sector is equal to the arc angle of 48°
The exterior angle is the supplement 180 - 48 = 132°
The isosceles triangle has two angles a of (180 - 132)/2 = 24°
This can be generalized to the angle between the chords is half of the arc angle when one chord is a diameter and the chords share a common endpoint.
