Question

IN THE GIVEN FIGURE ABCD , FIND THE VALUE OF X​

Answer 1

Step-by-step explanation:

80+70+70+x=360

x+220=360

x=140

Answer 2

Answer:

the value of x is 140°

Step-by-step explanation:

An exterior angle basically is formed by the intersection of any of the sides of a polygon and extension of the adjacent side of the chosen side. Interior and exterior angles formed within a pair of adjacent sides form a complete 180 degrees angle.

according to exterior angle property of a quadrilateral, the sum of exterior angles of a quadrilateral is 360°.

70° + 80° + 70° + x = 360°

220° + x = 360°

x = 360° - 220°

x = 140°
