Can some please give the correct answer? I don't know what I did wrong.

Use the following image to find the correct answer.

Find m∠A.

What is the degree measurement of m
Please show all of the work on how you got your answer. (You don't have to explain if you don't want to, just show the work on how you got your answer)

42 degrees

Step-by-step explanation:

Angle A is an inscribed angle of the arc BC.

As a rule of thumb, remember that the measure of all inscribed angles is half of the measure of the intercepted arc.

In this case, the intercepted arc is BC, which we know is 84 degrees. So, if the inscribed angle is half of that, then angle A = 84/2 = 42 degrees.

Hope this helps!

m < A = 42 degrees.

Step-by-step explanation:

The measure of the angle subtended by an arc on the circumference is ahlf of the measure of that arc.

16 is the absolute value
