Question

The measure of angles of a quadrilateral are (x+20)°, (x-20)°, (2x+5)° and (2x-5)°• Find the value of x

Answer 1

Answer:

6x=360

x=60

x+20=80

x-20=40

2x+5=165

2x-5=115

Answer 2

Sum of all angles in a quadrilateral is 360°

(x+20) + (x-20) + ( 2x+5) + (2x-5) = 360

2x+4x = 360

6x = 360

x = 60
