Question

The angles of a quadrilateralaeral are respectively 100 degree , 98 degree , 92 degree . Find the fourth angle

Answer 1

100+98+92+x=360
290+x=360
x=360-290
x=70

Answer 2

Answer:

First angle of Quadilateral = 100°

Second angle of Quadilateral = 98°

Third angle of Quadilateral = 92°

Fourth angle = ?

Solution for fourth angle :

• Let the measure of fourth angle be x°. We know that the sum of all angles of a quadilateral is 360° .

•°• 100 + 98 + 92 + x = 360

=> 290 + x = 360

=> x = 360 - 290

=> x = 70

Hence, the measure of the fourth angle is 70° .
