So try and recognize the pattern. For level 1, you have 1 box and 12 cans. In 2, you have 3 boxes and 36 cans. 12/1 is 12, 36/3 is 12 and so on. The # of boxes times 12 is the number of cans. The # of boxes in the display is equal to the total number of boxes in each level. Level 5 will mean 1+2+3+4+5=15. Level 6 is 1+2+3+4+5+6=21. So if 6 has 21 display boxes, we can do 21*12 and you will get 252. Your answer is E, 252 cans.
Let the base angle be x. If the obtuse angle is two and a half times the base angle, it will be 2.5x. In a triangle, all three angles will add up to 180. The third angle, the other base angle will be equal to x. So the equation will be:
x + x + 2.5x = 180
2x + 2.5x = 180
4.5x = 180
x = 40
If x = 40, then 2.5x = 100
The lines never intersect or touch should be the answer.
Hope this helps/works.
