Question

At 3 o'clock, the angle formed between the two hands of a clock is

• A. right
• B. acute
• C. obtuse
• D. left

Answer 1

The correct option is A right

$\Rightarrow$ A clock is a circle made of ${360}^o$. and that

$\Rightarrow$ Each number represents an angle and the separation between them is $\frac{360}{12}={30}^o$.

$\Rightarrow$ At $2:00$, the minute hand is on the $12$ and the hour hand is on the $3$.

$\Rightarrow$ The angle between two hands $=3\times {30}^o={90}^o$

$\Rightarrow$ At $3$ o'clock, the angle formed between the two hands of a clock is $rightangle.$
