## luisz 3 years ago In quadrilateral PQRS, the measure of angle S is 20 more than the average of the measures of the other three. What is the measure of angle S?

1. luisz

I guess I am posting alot of Geometry problems today

2. AriPotta

the sum of interior angles in a quadrilateral is 360

3. luisz

yep

4. AriPotta

so, with that, how would you set up the equation?

5. luisz

=360

6. luisz

hmm

7. cinar

140

8. luisz

that is an incorrect response

9. luisz

it is 105

10. luisz

but why

11. cinar

20+(a+b+c)/3=s

12. luisz

I set up the equation

13. luisz

3x/3+20+x+x+x=360

14. AriPotta

cinar is right :l

15. luisz

opps

16. luisz

4x=340

17. luisz

so

18. luisz

each angle equals 85 besides S

19. cinar

yes it is 105

20. luisz

85 times 3=255

21. luisz

+105=360

22. luisz

ty guys

23. AriPotta

don't listen to me, listen to cinar lol

24. luisz

where is that dog from?

25. cinar

a+b+c+s=360

26. luisz

What TV show?

27. AriPotta

martha speaks

28. luisz

nice
