If the measure of a tangent-chord angle is 68°, then what is the measure of the intercepted arc inside the angle?
2 answers:
Answer:
112°
Step-by-step explanation:
1/2(248 - 112) = 68
2 equations with 2 unknowns
x = intercepted arc, y = rest of the circle
x + y = 360
1/2 (y - x) = 68
1/2 ((360 - x) - x) =68
360 - 2x = 136
224 = 2x
112 = x
Answer:
113°,
Step-by-step explanation:
- tangent - chord angle is 68°,
