Answer:
The given angles of a quadrilateral are xo,(x−10)o,(x+30)o and 2xo.
We know, that sum of four interior angles of a quadrilateral is 360o.
∴ x+(x−10)+(x+30)+2x=360o
⇒ 5x+20o=360o
⇒ 5x=340o
⇒ x=5340o
⇒ x=68o.
Now, measure of an angles:
xo=68o,
(x−10)o=(68−10)o=58o,
(x+30)o=(68+30)o=98o
and 2xo=2(68o)=136o.
∴ The greatest angle is 136o.
