1.

The angle of a quadrilateral are in ap and the greatest angle is 120°.Express the angles in radian

Answer»

ANSWER:

so simple answer is 2π/3

Step-by-step explanation:

we know that

let be the angles are a-3d, a-d, a+d ,a+3d

given that

a + 3d=120..................(1)

we know that the sum of all angles is 2π

a-3d +a-d +a+d+ a+3d =2π

4a = 2π

a=π/2

from equation (1)

I hope it will be HELPFUL for you

if you SATISFIED with above explanation than please mark it as brainiest answer
