3.
4.For question 5, use the picture below. Find the value ofx.
5.m^64 = ( 5 x− 33 )◦,m^65 = ( 2 x+ 60 )◦- Are lineslandmparallel? If yes, how do you know?
For 7-12, what does the value ofxhave to be to make the lines parallel?
7.m^64 = ( 3 x− 7 )◦andm^65 = ( 5 x− 21 )◦
8.m^63 = ( 2 x− 1 )◦andm^66 = ( 4 x− 11 )◦
9.m^63 = ( 5 x− 2 )◦andm^66 = ( 3 x)◦
10.m^64 = (x− 7 )◦andm^65 = ( 5 x− 31 )◦
11.m^63 = ( 8 x− 12 )◦andm^66 = ( 7 x)◦
12.m^64 = ( 4 x− 17 )◦andm^65 = ( 5 x− 29 )◦For questions 13-15, use the picture below.
