Question

The three angles of a quadrilateral are 49°, 98°, and 117°. Find the fourth angle.


​

Answer 1

Answer:

therefore,fourth angle is 96°

Answer 2

Given :-

First angle = 49°

Second angle = 98°

Third angle = 117°

Fourth angle = ?

Let fourth angle be x

Solution :-

The sum of angles of a quadrilateral is 360°

Therefore,

First angle + Second angle + Third angle + Fourth angle = 360°

49° + 98° + 117° + x = 360°

264° + x = 360°

x = 360° - 264°

x = 96°

Fourth angle = x = 96°
