On a pie chart there are six sectors of which four angles are 30°, 45°, 60°, 90° and the remaining two angles are in the ratio 2:1. Find the smallest angles of the remaining two angles.
- A.
15^{o} - B.
30^{o} - C.
45^{o} - D.
60^{o}
Correct Answer: Option C
Explanation
30 + 45 + 60 + 90 + 2x + x = 360°
225 + 3x = 360
3x = 360 – 225
3x = 135
x = 45°
