A theorem called "inscribed angle theorem," states that angle θ is half of that of angle 2θ that subtends an identical arc on the circle.

So, ∠ABC = center angle * 1/2

The center angle is 192°, so substitute with that number and solve.

∠ABC = 192 * 1/2

∠ABC = 96°

Therefore, the answer is 96°

Best of Luck!

2/3 m + 7 = 29<br><br> help me please
melisa1 [442]

Answer:  M=33


Step-by-step explanation:

2/3m+7=29

       -7= -7      subtract 7 from both sides

2/3m=22   since you can not divide fractions you will simply put 22 over 1 and                  

                 multiply by the recipocal of 2/3.

3/2*2/3=22/1*3/2  the first part of this equation cancels each other out.

m=22/1*3/2 two can go into 22, 11 and once into itself times so simplify

m=11/1*3/1 multiply numerators

m=33/1 or 33
