Question

Find the value of x. Then find mAB.

Answer 1

Answer:

16x - 5 = 15x

16x - 16x -5 = 15x - 16x

-5 = -x

-5 / -1 = -x / -1

x = 5

mAB = 5(5)

mAB = 25°

Step-by-step explanation:

1. set arc FA and arc CD equal to each other.

2. subtract 16x from both sides.

3. divide both sides by -1 to get x.

4. replace x by its value to solve for mAB.
