Question

find the fourth angle of quadrilateral if the remaining angles are 80°,50°,100°​

Answer 1

Answer:

FACT: sum of all angles of quadrilateral is 360 degree

          80+50+100+x=360

           x=130 degree

therefore, fourth angle is 130 degree

Step-by-step explanation:

Answer 2

Answer:

Sum Of Angles Of Quadrilateral = 360, 80+50+100+x = 360

360=230+x

x=130

Step-by-step explanation:

Let The fourth Angle Be X

Sum Of All Angles Of A Quadrilateral = 360°

Therefore: 80+50+100+x = 360

230+x=360

x=360-230

x=130°

Answer) The fourth Angle is 130°

Verification:

80+50+100+130=360
