He’d make 13 packages; each one would have 1 player and 3 headphones.
Well i think is a) <span>m3
I'm not sure, i hope this help

I would say a triangle with two right angles because a triangle's angles add to 180 degrees. If a triangle has two right angles, it means that two angles will be 90 degrees, which add to 180 degrees. A triangle must have three angles and sides, and it is not possible for the last angle to be 0 degrees.
Hope this helps
