Question

at five o clock the hand of aclock make an obtuse angle and a reflex angle find the measure of each of these angles

Answer 1

At 5 o'clock
Let one angle=x
Sec. Angle =360-x
Half of clock is =180°
And is distributed in 30°each
Therefore 5×30=150°
Second angle = 360-150=210°

Answer 2

Answer:

At 5 o'clock

Let one angle=x

Sec. Angle =360-x
