## Danman325 3 years ago In the figure, circle O has radius 6 units. Chord CD has length 8 units and is parallel to segment KB. If KA = 12 units and points K, A, O and B are collinear, what is the area of triangle KDC? Express your answer in simplest radical form.

Yup

4. Danman325

It says$8\sqrt5$

5. moneybird

ok

8. moneybird

CD = 8 8 * 2 sqrt(5) / 2 = 8 sqrt(5)
