Someone which statements are true? check all that apply.

A) arc CB = 120°

              C) <COB = 2(m<CAB)

              D) <COB = 120°

Step-by-step explanation:

The measure of an inscribed angle is half the measure of its intercepted arc

⇆ The measure of an arc is twice the measure of its inscribed angle.

Thus, since <CAB = 60°, then arc CB = 120°   OPTION A

The measure of a central angle is congruent to its arc

⇆ The measure of an arc is congruent to the central angle.

Thus, since arc CB = 120°, then <COB = 120°  OPTION D

Since <COB = 120°, and <CAB = 60°,

then <COB = 2(m<CAB)  OPTION C

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !
