Question

the angles of a quadrilateral are in A.P whose common difference is 10. Fond.the angles

Answer 1

Answer:

Let the 1st angle be x

then 2nd angle = x+10

3rd angle = x + 20

4th angle = x + 30

A/q

x + x + 10 + x + 20 + x + 30 = 360

=> 4x + 60 = 360

=> 4x = 360 - 60

=> 4x = 300

=> x = 300/4

x = 75

Hence,

1st angle = x = 75°

2nd angle = x+10 = 85°

3rd angle = x + 20 = 95°

4th angle = x + 30 = 105°
