Question

f the angles of a quadrilateral are in A.P with common difference 10 then the sum of angles is​

Answer 1

Step-by-step explanation:

Let one of the angle is a

So there angles are a+10,a+20,a+30

a+a+10+a+20+a+30=360

4a+60=360

4a=300

∴a=75

First angle=75∘

Second angle=75+10=85∘

Third angle=85+10=95∘

Forth angle=95+10=105∘
