If central right angle a intercepts bc, which measures 113, then right angle a measures

Arc's get their angle measurement from the central angle they're in.

so if the arcBC which is 113°, has a central angle of A, that simply means that her central angle is 113°.

The answer is 25uthere is no v in the question

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
