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°
