Question

If angles of a linear pair are equal, then the measure of each angle is

30

45

60

90


​

Answer 1

Step-by-step explanation:

So, correct Answer is = 90

Answer 2

Answer :

If angles of a linear pair are equal, then the measure of each angle is 90°

Proof :

A linear pair always as a sum of 180°

As both angle are equal,

let, both the angles be x°

So, we can derive a equation from the given statement, i.e -

$x + x = 180\\2x = 180\\x = \frac{180}{2} \\\\x = 90$

⇒If angles of a linear pair are equal, then the measure of each angle would be 90°
