Answer:
Alternate interior: angle 2 and angle 13
Vertical: angle 12 and angle 15
Alternate exterior: angle 5 and angle 10
No relationship: angle 1 and angle 16
Corresponding: angle 14 and angle 16
Consecutive interior: angle 4 and angle 11
This isn't true because the exact answer of a system is where the lines cross each other, not where they cross a grid.
5 packs of erasers and 3 packs of pencils each will have 60
In the right triangle, one of the angles has measure 60 deg, so the remaining angle has measure 30 deg. In such a 30-60-90 triangle, the sides occur in a ratio of 1 to
to 2 (shorter leg to longer leg to hypotenuse). This means


making the answer C.
