Answer:
She read 15 fiction books
Step-by-step explanation:
Multiply 10 x 3 = 30
so she reads 30 non fiction books and she reads half as many fiction books as she reads nonfiction.
Divide 30/2=15
any point that is on the circle will have a distance of "radius" units, namely 13 units, since the radius is just that.

The measure of angle KNM is 155 since the measure of an arc is the measure of its central angle. Just add 83 degrees to 72 degrees.
