Question

If measure of the arc AB = 80o, and the measure of arc CE = 16o, which is the measure of EDC?

Answer 1

This is a power theorem. Angle EDC will be equal to (arc AB + arc CE)/2

(80+16)/2 = 48

Answer 2

32 deg

Answer 3

Given a circle with a diameter of 6, which is the circumference?

Answer 4

Circumference of circle = Pi X D (3.1416 X Diameter of 6) = 18.8496
18and 1/2 inches

3.14 is constant,

thus,
6x3.14=18.84
18.84 is the answer.

Answer 5

ow okay never mind i got it thank! = ]
