I NEED HELP PLEASE ! :)

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°

step-by-step explanation:

b and c

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
