So 
So

The magnitude of the claimed earthquake would be 13.67.
Sum measure of interior angles of traingle is 180° according to this rule ; sum measure of interior angles = (n-2)180 where n is the no. of sides
(3-2)180
=180°
So

The sum of an interior and exterior angle equals to 180°
According to this
