You do know that the 4 sides of a parallelogram equal 360 degrees?

OpenStudy (anonymous):

yea but i only get the value of one of them i'm really confused

OpenStudy (anonymous):

some help please?

OpenStudy (anonymous):

you have not given the whole question!

OpenStudy (anonymous):

yea that's all they gave me to find the value of a

OpenStudy (anonymous):

my options are a) 96 b)192 C)101 D)200

OpenStudy (anonymous):

Maybe, and I am only suggesting here: b degrees = 196 degrees a degrees = d degrees + 96 degrees c degrees + d degrees = 99 degrees

OpenStudy (anonymous):

Thew common denominator is d degrees

OpenStudy (anonymous):

the total of a and c is 164 degrees

all the information is there that you need

OpenStudy (amistre64):

the subtended arc of an angle is 2times the angles.

OpenStudy (amistre64):

as such, since you have 4 corners, opposite corners add up to 180 in order to have a complete circle of 360

OpenStudy (amistre64):

|dw:1427903739366:dw|

OpenStudy (amistre64):

2a + 2b = 360 a+b = 180

OpenStudy (amistre64):

as such: 2(100) = 99+a, solve for a

OpenStudy (anonymous):

so a=101?
