The ABD angle is based on the AD arc, the degree measure of which is equal to two values of the ABD angle.
Arc AD = 14 * 2 = 28.
The CAD angle is based on the CD arc, the degree measure of which is equal to two values of the CAD angle.
Arc CD = 30 * 2 = 60.
The angle ABC is based on the arc AC, the degree measure of which is equal to the sum of the arcs AD and CD.
Arc AC = 28 + 60 = 88
Then the angle ABC is equal to half of the degree measure of the arc AC.
Angle ABC = 88/2 = 440.
Answer: Angle ABC is 44.
