Answer:
71
so there's a right angle and 19° i added them and got 109°. and remember a triangle is 180° so i did 180-109
Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40
40+89.6=129.6
the area of the bottom is 7*8=56
the total area is 129.6+56=185.6
I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice.
I'd suggest 185.6, the total surface area.
-1/2 ÷9/5
=-1/2*5/9
=-5/18. answer.
-1*5 =5 numerator
2*9=18 denominator
X=-6(y-2)
x=-6y+12
x-12=-6y
-1/6x+2=f^-1(x)
