Chords and intersect in circle O as shown in the diagram. Two of the angle measurements are marked. What is mCED?

jenyasd209 [6]

we know that

The measure of the interior angle is the half sum of the arcs comprising it and its opposite

m∠CED= $\frac{1}{2} *(arc\ AB+arc\ CD)$

see the attached figure with letters to better understand the problem

$arc\ AB=82$ ° ------> by central angle

$arc\ CD=48$ ° ------> by central angle

Substitute the values in the formula above

m∠CED= $\frac{1}{2} *(82+48)$

m∠CED= $\frac{1}{2} *130$

m∠CED= $65$ °

therefore

<u>the answer is</u>

m∠CED= $65$ °
