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?

OpenStudy (anonymous):

I guess I am posting alot of Geometry problems today

OpenStudy (aripotta):

the sum of interior angles in a quadrilateral is 360

OpenStudy (anonymous):

yep

OpenStudy (aripotta):

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

OpenStudy (anonymous):

=360

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

140

OpenStudy (anonymous):

that is an incorrect response

OpenStudy (anonymous):

it is 105

OpenStudy (anonymous):

but why

OpenStudy (anonymous):

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

OpenStudy (anonymous):

I set up the equation

OpenStudy (anonymous):

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

OpenStudy (aripotta):

cinar is right :l

OpenStudy (anonymous):

opps

OpenStudy (anonymous):

4x=340

OpenStudy (anonymous):

so

OpenStudy (anonymous):

each angle equals 85 besides S

OpenStudy (anonymous):

yes it is 105

OpenStudy (anonymous):

85 times 3=255

OpenStudy (anonymous):

+105=360

OpenStudy (anonymous):

ty guys

OpenStudy (aripotta):

don't listen to me, listen to cinar lol

OpenStudy (anonymous):

where is that dog from?

OpenStudy (anonymous):

a+b+c+s=360

OpenStudy (anonymous):

What TV show?
