Measure Of Arc BC Isdegrees class=

Sagot :

Answer:

A. 98

Step-by-step explanation:

Based on inscribed angle theorem, the inscribed angle (<D) is half of the angle subtended by the arc BC. That is:

m<D = ½(BC)

m<D is given as 49°

Thus,

49° = ½(BC)

Multiply both sides by 2

2(49) = BC

98° = BC

BC = 98°
