Answer:
Clock is a whole circle nd we know that measure of a whole circle = 360°
and measure of half circle =180°
so half circle of a clock is 6 o'clock
and between the two numbers 5 and 6 there are 5 small dots or minutes in a clock..
let us consider each small dot or minute =1°
so 5 dots =5°
so if 6o clock = 180° and there are 5 small dots between 5 and 6 which = 1° then
5 o clock = (180–5)°
= 175°
As we know that 5 o clock which is more than 90° but less than 180° is an obtuse angle and the other angle forming is a reflex angle whose measure will be more than 180° but less than 360°
So the reflex angle = (360–175)°
= 185°
Hence the measure of the obtuse angle is 175° and the reflex angle formed on a clock showing 5oclock is 185° respectively
