Answer:
x = 22
Step-by-step explanation:
line AD is 180°
so 40° + (5x + 30°) = 180°
solve for x.
5x = 180-30-40
5x= 110
x = 110/5
x= 22

Answer:
height = 10.5 cm (for open-top container)
Step-by-step explanation:
The area of the base is ...
A = πr²
The lateral area is ...
A = 2πrh
We want the ratio of these to be 1:6, so we have ...
πr²/(2πrh) = 1/6
6πr² = 2πrh . . . cross multiply
h = 3r . . . . . . . divide by 2πr
h = 3(3.5 cm) = 10.5 cm
The height is 10.5 cm.
