Question

14

The angles of a quadrilateral are 5xo , 5(x + 2)o , (6x -20)o and

 6(x + 3)o  respectively.

Find the value of x.​

Answer 1

Answer:

Step-by-step explanation:

we know that the sum f the interior angles of a quadrilateral is 360 degrees

so ,5x+5(x+2)+6x-20+6(x+3)=360

5x+5x+10+6x-20+6x+18=360

22x+8=360

22x=352

x=352/22=16
