Question

What is \[\dfrac{1}{3}\] of a right angle?

Answer 1

Hint: Given is a simple question related to a right angle. Right angle is \[{90^ \circ }\]. We need to find the \[\dfrac{1}{3}\] of the given angle. It is nothing but the use of “of” operator. We have to multiply the given angle by \[\dfrac{1}{3}\] . and the answer will be there.

Complete step by step solution:
Given is a right angle.
Right angle equals to \[{90^ \circ }\].
Now we have to find \[\dfrac{1}{3}\] of this angle.
So \[ = \dfrac{1}{3} \times {90^ \circ }\]
Now on dividing by 3 we get,
\[ = {30^ \circ }\]
This is the correct answer.
So, the correct answer is “\[ {30^ \circ }\]”.

Note: Note that “of” is not only a word it is used as an operator in mathematics. We know that the fractions are generally known as half, quarter, three-forth, one-third etc. also note the resulting answer is also an angle.
