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?

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|

30?

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: \(\large x+x=2x\)

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?

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
