Question

Three angles of a quadrilateral are 34 digree , 70 digree and 126 digree , find the fourth angle

Answer 1

Answer:

Let the fourth angle be x

→34+70+126+x=360

→230+x=360

→x=130

Answer 2

Answer:

the sum of quadrilateral =360

then 1st angle =34

2nd angle =70

3rd angle=126

4th angle =?(let it be x

angle1+angle2+angle3+angle4=360

34+70+126+x=360

230+x=360

so,x=360-230

x=130
