Question

5. The angles of a quadrilateral are (2x + 4)º,
(2x – 1), (2x + 5)º and 2(3x + 2)°,
respectively. Find the value of x.​

Answer 1

Answer:

x=31°

Step-by-step explanation:

sum of angles of a quadrilateral=360°

(2x+4)+(2x-1)+(2x+5)+2(3x+2)=360

  12x+12=360

     12(x+1)=360

       x+1=30

         x=31°
