Question

Measures of the two angles between hour and minute hands of a clock at 9 O’ clock are

Answer 1

Answer:

A clock is a circle made of 360 degrees, and that each number represents an angle and the separation between them is 360/12 = 30.

So, at 9:00, the minute hand is on the 12 and the hour hand is on the 9.

=> 9*30=270°(if we start clock wise)

(12-9)*30=3*30=90°(if we start anticlockwise wise)

Answer 2

Given :

Measures of the two angles between an hour and minute hands of a clock at 9 O’ clock are

Solution:

The angle between the two hands of a clock is regarded as "Right Angle" When the time in the clock is 9'O clock.

When the time is 9'o clock, the hour hand is at 9 and the minute's hand is at 12.

Right Angle:-

Right Angle is an angle which measures 90°

One Right Angle is equaled to two Acute angles.

Right Angle = 90°

Any two acute angles = 45° + 45° = 90°

Angles :-

Acute Angle:- An angle that measures between 0° and 90°.

Right Angle:- An angle which measures 90°

Obtuse Angle:- An angle that measures between 90° and 180°.

Straight Angle:- An angle which measures 180°
