Answer:
m∠3 = 24°
Step-by-step explanation:
By the theorem,
"Intercepted arc measures the double of the inscribed angle formed by two chords meeting at one point of the circle."
In the given picture,
∠3 is the inscribed angle subtended by the arc ED and is the intercepted arc.
Therefore, m∠3 = ![\frac{1}{2}m(\text{arc}ED)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dm%28%5Ctext%7Barc%7DED%29)
m∠3 = ![\frac{1}{2}(48)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2848%29)
= 24°
Measure of angle 3 is 24 degrees.
