In the diagram above, O is the center of the circle, BOC is a diameter and angle ADC is 37o
What is ACB?

  • A.
    147o
  • B.
    127o
  • C.
    65o
  • D.
    53o
  • E.
    37o
Correct Answer: Option D
Explanation

From the figure (< ABC = < ADC = 37°) (angles on the same segment)

(< BCA = 90°) (angle in semi-circle)

(therefore) In (Delta ABC), (< ACB = 180° – (37° + 90°))

= 53°
