Question

Find each of them
In a quadrilateral, the angles arex". (x+10). (x+20).(x +30)". Find the angles.​

Answer 1

Step-by-step explanation:

By Angle Sum Property of Quadrilateral, the sum of angles of a Quadrilateral is always 360.

Hence,

$x + x + 10 + x + 20 + x + 30 = 360 \\ 4x + 60 = 360 \\ 4x = 300 \\ x = \frac{300}{4} = 75$

Hence, x=75
