nin am i right >.>
m || n means that they are parallel
two different lines are parallel if their slopes are the same
show your solution
3x-5=145 <--- this the setup 3x=15<----add 5 to both sides divide both sides by 3 x=50
how did you get 15?
i meant 150
1. The angles are same side interior angles. If they are supplementary, the lines are parallel. 2. The angles are corresponding angles. If the angles are congruent, the lines are parallel. 3. The angles are alternate exterior angles. If the angles are congruent ,the lines are parallel.
The equation 3x - 5 = 145 is correct.
3x - 5 = 145 Add 5 to both sides. Then divide both sides by 3.
ye, then some details follow like the one on this website http://www.mathsisfun.com/geometry/parallel-lines.html but analytically, slopes are the same when lines are parallel
x = 50 is correct.
you don't need to keep giving me medals I prefer that you learn than my receiving of medals
