Which angle could you show is congruent to ∠11 to prove a || b?

OpenStudy (anonymous):

OpenStudy (anonymous):

∠9 and ∠8 are what kind of angles?

OpenStudy (anonymous):

What relationship between ∠6 and ∠11 show c || d?

OpenStudy (anonymous):

okay thats all!

OpenStudy (anonymous):

One question per thread my friend

OpenStudy (anonymous):

sorry im in a serious rush please help me!!

OpenStudy (anonymous):

For the first one, there are two steps. Finding z, and then finding x. Z is pretty easy to find. |dw:1436296541891:dw|

OpenStudy (anonymous):

30?

OpenStudy (anonymous):

Correct. And since the total of the triangle is 180, that means that |dw:1436296739773:dw| Can you solve for x then?

OpenStudy (anonymous):

130?

OpenStudy (anonymous):

Show me your steps.

OpenStudy (anonymous):

20 plus 30 equals 50 and 180 minus 50 is 130

OpenStudy (anonymous):

So that means that \[\large x+x=130\] Hint: \(\large x+x=2x\)

OpenStudy (anonymous):

65?

OpenStudy (anonymous):

Correct! So now plug in z=30 and x=65 into the original angles of the triangle to solve it.

OpenStudy (anonymous):

If we're just solving for z and x then we're done though

OpenStudy (anonymous):

85?

OpenStudy (anonymous):

|dw:1436297145923:dw|

OpenStudy (anonymous):

it says to input the answer as x,z so would it be 30,65

OpenStudy (anonymous):

If you're inputting as x,z then 65,30

OpenStudy (anonymous):

okay thanks
