If x°,105°,43° and 62° are angles of a quadrilateral. Find the value of x

Answer 1

The sum of angles in a quadrilateral is 360°.

Therefore,

x + 105 + 43 + 62 = 360

Simplifying the left-hand side,

210 + x = 360

Subtracting 210 from both sides,

x = 150

Therefore, the value of x is 150 degrees.
