Question

If the angles of a quadrilateral are x°,x-20°,x-30°,x+10°, then find x

Answer 1

Sum of all angles of an quadrilateral = 360°


=> x + x - 20 + x - 30 + x + 10 = 360


=> 4x - 40 = 360

=> x - 10 = 90

=> x = 100°




Angles are :-

x = 100°
x - 20 = 80°
x - 30 = 70°
x + 10 = 110°

Answer 2

Hey Mate !!


Angles of Quadrilateral are : x°,x-20°,x-30°,x+10°

Sum of all angles in Quadrilateral = 360

ATP,

x° + x-20° + x-30° + x+10° = 360

4x - 40 = 360

4x = 360 + 40

4x = 400

x = 400/4

x = 100

Angles are :

x = 100

x - 20 = 100 - 20 = 80

x - 30 = 100 - 30 = 70

x + 10 = 100 + 10 = 110
