1) 3+17= 20
2) 40-15= 25
3) 3 x 20= 60
4) 35/5= 7
5) 2 x 6= 1
12= 1
1/12.
Supplementary angle must add up to 180 so the supplement will be 108 degrees. 180-72=108.

Answer:
m
Step-by-step explanation:
Let
Bas length of box=b
Height of box=h
Material used in constructing of box=36 square m
We have to find the height h and base length b of the box to maximize the volume of box.
Surface area of box=




Volume of box, V=
Substitute the values


Differentiate w. r.t b







The negative value of b is not possible because length cannot be negative.
Again differentiate w.r.t b

At

Hence, the volume of box is maximum at
.
