Answer:
121°
Step-by-step explanation:
- We have been given a chord and tangent to a circle, and also a minor arc measure that is equal to 118°
- We know that; An angle formed by a secant and tangent of circle is half of the measure of intercepted arc.
Therefore; ∠ x = 1/2 mABC
- We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Thus; 360° - 118° = 242°
Using the formula; ∠ x = 1/2 mABC
Then; d = 242/2
= 121°
