Question

Angles of a quadrilateral are (x+60), 20(x- 15 )
(4x) and 6 (x+3)
Find value of x
ii. find each angle of quadrilateral​

Answer 1

Step-by-step explanation:

sum of angles in a quadrilateral is 360degrees

so, x+60+20x-15+4x+6x+18=360

31x+63=360

31x= 360-63

31x= 297

x = 297/31

x = 9.58

substitute in the values
