geometry help?

OpenStudy (anonymous):

Find the values of the variables in the parallelogram. The diagram is not drawn to scale.

OpenStudy (rea201):

Where is the diagram I can help you!!

@Rea201

OpenStudy (rea201):

The first variable we can find is y.

OpenStudy (rea201):

Do you have any idea what we do to find it?

OpenStudy (anonymous):

nope

OpenStudy (rea201):

If you don't it's fine I can teach you

Opposite angles of a parallelogram are equivalent, so <z=the angle opposite (which is 109 degrees). Alternate interior angles are congruent, so 33=x. Finally, the angles of a triangle add up to 180, so y = 180-(109+33).

Directrix (directrix):

Have you found z and y? @thelaw2 Maybe I should look above. :)

Directrix (directrix):

I see z. What is y?

OpenStudy (anonymous):

Nope :(

Directrix (directrix):

I worked this. Let me check my answers against those here. Just a second.

OpenStudy (anonymous):

ok

Directrix (directrix):

So far in this thread, z = 33, z = 109, and y has to be found. So, solve this: y = 180-(109+33)

Directrix (directrix):

y = ? @thelaw2

OpenStudy (anonymous):

38? @Directrix

Directrix (directrix):

y = 38, yes, that is what I got.

OpenStudy (anonymous):

thanks :) @Directrix

Directrix (directrix):

You are welcome.
