Question

Find the value of x ​

Answer 1

Answer:

Value of x = 23

Step-by-step explanation:

The given figure is a quadrilateral. So, following the Angle sum property of Quadrilateral, we can find the value of x

Angle sum property of quadrilateral is that all the angles of the quadrilateral and sum up and make 360°

➨ (3x + 20)° + 4x° + (2x + 18)° + 5x° = 360°

➨ 3x + 20 + 4x + 2x + 18 + 5x = 360

➨ 7x + 2x + 5x + 20 + 18 = 360

➨ 14x + 38 = 360

➨ 14x = 360 - 38

➨ 14x = 322

➨ x = 322/14

➨ x = 23

$\therefore$ Value of x = 23
