The angle bisector of ACB intersects the circle at point M Find CM.

 

Hello Guest!

 

Point C is on the periphery of the Thales circle of diameter AB.

Triangle ABC is a right triangle. The following applies:

\(\overline{AB}=\sqrt{\overline{AC}\ ^2+\overline{BC}\ ^2}=\sqrt{8^2+4^2}=\sqrt{64+16}=8.944\)
