Given the fact that 95 is on the right side of the line
the left side would be 85 in which you would
add 85 to 60 which would be 145
then subtract 145 from 180 and you'll get
35 degrees as your missing angle so
X = 35
Can or bottle? A can will be the calculation for the surface area of a cylinder which is A=

if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that
First equation: x=-y+8
Second equation: on the picture
Purple flowers: black flowers = 4:8 = 108
4 + 8 = 12
108 / 12 = 9.
9 x 4 = 36.
36 of the flowers are purple.
