In the diagram above, O is the center of the circle, BOC is a diameter and angle ADC is 37o What is ACB?
Answer Details
Since BOC is a diameter, then angle BAC is 90 degrees (as it is an inscribed angle that subtends a diameter).
Also, angle ADC is 37 degrees (given).
Therefore, angle ACB can be found using the fact that the angles in a triangle sum to 180 degrees. Thus:
angle ACB = 180 - angle BAC - angle ADC
= 180 - 90 - 37
= 53 degrees
Therefore, the answer is 53 degrees.
