12.8

Step-by-step explanation:

tan(theta) = opposite/adjacent

in this question, theta should be 59 deg, opposite is EF which is x, and adjacent is DE which is 7.7

So plug in these data

tan(59deg) = x/7.7 ==> x = 7.7 * tan(59deg) ~~12.8

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
