The value of angle ABC is determined as 17 ⁰.
How to calculate the arc angle ABC
The value of angle ABC is calculated by applying the following formula as follows.
The value of arc CD is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.
m ∠ABC = 1/2 x (arc AC)
The given parameters include;
arc AC = 34⁰.
The value of angle ABC is calculated as;
m ∠ABC = 1/2 x 34
m ∠ABC = 17 ⁰
