Answer:  x = 30

======================================================

Explanation:

In any quadrilateral, the four angles always add to 360

P+Q+R+S = 360

x+5x+x+5x = 360

12x = 360

x = 360/12

x = 30

This means

P = R = x = 30

Q = S = 5x = 5*30 = 150

So, P+Q+R+S = 30+150+30+150 = 360 which helps confirm the answer.

Answer:

x = 30

Step-by-step explanation:

the sum of all angles is 360

the picture shows that the sum equals 12x

12x=360

x= 360/12

x = 30
