Question

The measure of AXB is 196°. What is the measure of ZABC, the tangent- chord angle?

Answer 1

Answer:

B

Step-by-step explanation:

The tangent- chord angle is calculated as

∠ABC = 0.5( m arc AXB) = 0.5 × 196° = 98° → B

Answer 2

Answer: 98°

Step-by-step explanation:

Since the angle is formed by a tangent and a chord which intersect on a circle, then the measure of <ABC = AXB / 2

<ABC = 196 / 2

<ABC = 98°
