Question

14. Sum of two angles of a quadrilateral in the
ratio 1:3 is 200°. If the other two angles of the
quadrilateral are equal, find all the four angles of
the quadrilateral. Also, find the measure of all the
exterior angles.​

Answer 1

Answer:

let the equal angles be x

according to question

1:3 is 200

therefore ,

200+2x = 360

2x =360-200 = 160

x = 160/2 = 80

Hence , the equal angles are 80 degree

and other 2 are

1x + 3x = 200

4x = 200

x = 200/4 = 50

therefore

1x is 50

3x is 150
