Two consecutive angles of a parallelogram have measures 2(x+12) and 2(5x+6) respectively. Find the measures of the angles.

Reiny,
This question has the identical structure as the one I just answered for you.
Surely you can follow that example.
Let me know what answer you got. 
geometry 
jessica,
my answer is x=5 is it correct?

geometry 
Reiny,
no,
when subbing that back in you would get angles of 34 and 62, which obviously do not add up to 180 as they should
How did you possibly get x = 5 ?

jessica,
This is what I did 2(x+12)= 2(5x+6)
2x+24+10x+12
12x=60
x=5
If not correct cn u give me the right one?...tnx

Dr Russ,
Try it exactly the same way as the other one
2(x+12) + 2(5x+6) =180
2x+24+10x+12 =180
12x+36=180
12x=144
x=12
which gives 48 and 132 as the angles.

hello tulog ka ba?
