Answer:

m<ADB = 25 degrees

Step-by-step explanation:

<ADB has two different intercepted arcs: AB and the unlabeled one that has a measure of 20. To find the actual measure of the angle, we must find the difference between these arcs and divide by 2.

70-20 = 50

50/2 = 25

Applying the angle of intersecting secants theorem, the measure of angle ADB in the diagram is: A. m∠ADB = 25°

What is the Angle of Intersecting Secants Theorem?

When two secants meet at a point outside a circle, the measure of angle formed at that point is half the positive difference of the intercepted arcs, based on the angle of intersecting secants theorem.

m∠ADB = 1/2(70 - 20)

m∠ADB = 1/2(50)

m∠ADB = 25°
