Question

Angles of a quadrilateral are 100°,120°,x°,and (x+20)°.find the value of x.

Answer 1

Answer:

the value of x is 60° for the given question

Answer 2

Step-by-step explanation:

sum of the angles in a quadrilateral =360°

so 100°+120°+x+x+20°=360°

240°+2x=360°

x=60°

hence 100°,120°,60°,80° are the angles of the quadrilateral
