I have another question! :/

OpenStudy (anonymous):

rishavraj (rishavraj):

u see in a parallelogram opposite angles are equal

rishavraj (rishavraj):

so <ABC = <ADC and also adjacent angles adds to 180

OpenStudy (scoobydo):

192 because 2x+100=2times1=2+100=102 and 6x+84=6times1=6+ 84=90 so, 90+102=192

rishavraj (rishavraj):

oops sorry ...I wrote the value in negative .

OpenStudy (scoobydo):

no because I had the SAME question yesterday and I got an A

OpenStudy (anonymous):

Oh thanks! , you didn't have to give the answer just the equation lol

rishavraj (rishavraj):

hold on thts not the answer

OpenStudy (anonymous):

Oh hold on I believe the question should be 2x+100+6x+84=180?

OpenStudy (anonymous):

*equation

rishavraj (rishavraj):

u see <ABC = <ADC so 2x + 100 = 6x + 84 from here u will get x = 4 so <ADC = 108 and also <ADC + <BCD = 180 plug the value of <ADC and get the value of <BCD

rishavraj (rishavraj):

see in a parallelogram opposite angles are equal... and <ADC and <ABC are opposite angles ......

OpenStudy (scoobydo):

see told u

rishavraj (rishavraj):

so the answer is 72

rishavraj (rishavraj):

@scoobydo ur solution makes no sense.... no offense at all :)

rishavraj (rishavraj):

@OTAKUSUCKSATMath u got tht??? :/

OpenStudy (anonymous):

Yea I was solving to make sure! thank you! so 72?

rishavraj (rishavraj):

yup :))) see in a parallelogram opposite angles are equal and sum of adjacent angles is 180

OpenStudy (anonymous):

Okay thank you soooo much!
