Question

in a quadrilateral the angles are x, (x+10),(x+20),(x+30).find the angle​

Answer 1

As we know sum of all the angles of quadrilateral is 360° we can find x using this,

x+(x+10)+(x+20)+(x+30)=360

4x+60=360

4x=300

x=75.

So the angles of quadrilateral are 75,85,95&105.

Answer 2

We know that sum of all angles of a quadrilateral is 360°.

So, according to the problem,

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

4x + 60 = 360

4x = 360 - 60 = 300

x = 300/4 = 75°

First angle = x = 75°

Second angle = x + 10 = 85°

Third angle = x + 20 = 95°

Fourth angle = x + 30 = 105°
