The sum of the four angle measures of any convex quadrilateral is 360 degrees. Suppose that a convex quadrilateral has angle measures of 60, 6y+10, and 8y-2 degrees. Write an expression for the degree measure of the fourth angle.

will.h · Answer

well so they want you to write an expressions for that fourth angle and the angle must measure 60
yet i think they gave us all the terms and they want us to find the fourth!
hmm not so sure here but i will try 
60 + 6y+10 + 8y - 2 = 360
14y +68 = 360 
14y = 292
y = 20.857

bruh this looks confusing

will.h · Answer

wait wouldn't the fourth angle be just y! since it is unknown

ebonyserrano · Answer

no you did a great job, i understand the process of how you did

ebonyserrano · Answer

and yes

will.h · Answer

really so it is just y?

will.h · Answer

see if thats right

ebonyserrano · Answer

so what would the expression be?

will.h · Answer

we can't possibly figue out it is just (y)

how can we determine that other angle expression!

ebonyserrano · Answer

it would be -14y+292

will.h · Answer

you can have it as (y) only that would make sense 

60 + y + 8y -2 + 6y+10 = 360
15y +68 = 360
15y = 292
y = 19.4666666667
