Correct Answer: C
At 8:30, the hour hand is at 255°, minute hand at 180°; the angle between them is 75°, but accounting for the standard clock-angle formula the marked answer is 75° per option (C).
Q119.If the sum of two angles is 180°, they are called?
Correct Answer: D
Two angles are supplementary when their measures add up to 180 degrees. They are complementary when they add up to 90 degrees.
Q120.If each interior angle of a regular polygon is 162°, how many sides does the polygon have?
Correct Answer: A
The formula for each interior angle is (n - 2) * 180 / n = 162. Multiplying gives 180n - 360 = 162n -> 18n = 360 -> n = 20 sides.
