Question

Angle CCC is inscribed in circle OOO.

\overline{AB}
AB
start overline, A, B, end overline is a diameter of circle OOO.
What is the measure of \angle A∠Aangle, A?

Answer 1

43

Explanation:

angle c=90 because it is an angle gotten from the two ends of a diameter

sum of angles in a triangle is 180

since an angle is 90 the other two angles sum up to 90

angle a =90-37=43
