The measure of ∠1 =

60
120
240

The measurement of ∠1 is half of the central angle's length 120

120/2 = 60

60° is your answer

Reason: This is because an inscribed angle is half of the arc length.
               A central angle is the same measurement as the arc length.

hope this helps

The answer would be (c)

step-by-step explanation:

when the line is solid:

it's either < or >

when the line is dashed:

it's either < or >

about the problem:

since the line is solid, that means it's either < or >
