Opposite angles are equal to each other. Then use the property that the angle of a straight line is 180 degrees.

OpenStudy (anonymous):

can you help me set it up ? @PhysicsGuru

OpenStudy (anonymous):

Ok look at the angles 2x - 3 = 129 (Opposite Angles) Then use the property of the angle degree of a line is 180: 3y +129 = 180 Solve for y and x

OpenStudy (anonymous):

what im getting isn't one of the answers .. @PhysicsGuru

OpenStudy (anonymous):

Using the above you will get one of the answers. What are the algebra steps you are doing?

OpenStudy (anonymous):

i subtracted then divided . @PhysicsGuru

OpenStudy (anonymous):

you would add 3 then divide You would subtract 129 and then divide

OpenStudy (anonymous):

add 3 to both sides? @PhysicsGuru

OpenStudy (anonymous):

what wait ?

OpenStudy (anonymous):

2x - 3 + 3 = 129 + 3 -> 2x = 132 -> x = 132 / 2

OpenStudy (anonymous):

x=66 . @PhysicsGuru you'll have to forgive me ive missed a whole year of school lol

OpenStudy (anonymous):

yes that is the x value

OpenStudy (anonymous):

y=17 ... @PhysicsGuru

OpenStudy (anonymous):

correct
