Explanation:
The sum of the interior angles of a quadrilateral is , so that from the given question:
<A + <B + <C + <D =
(2x + 35) + (3x - 5) + (x + 10) + (4x + 20) =
10x + 60 =
10x = - 60
= 300
x =
= 30
x =
So that,
<A = (2x + 35) = (2*30 + 35) =
<B = (3x - 5) = (3*30 - 5) =
<C = (x + 10) = (30 + 10) =
<D = (4x + 20) = (4*30 + 20) =
Thus,
