Answer:

x = 34

Step-by-step explanation:

ΔABD and ΔBCD are both isosceles triangles

In ΔABD

AB =AD, hence ∠ABD = ∠ADB ( base angles are equal )

∠ABD = \frac{180-44}{2} = \frac{136}{2} = 68°

∠DBC = 180° - 68° = 112° ( straight angle )

∠BCD = x = \frac{180-112}{2} = \frac{68}{2} = 34

The US standard can is 4.83 inches high, 2.13 inches in diameter at the lid, and 2.60 inches in diameter at the widest point of
rewona [7]
The first thing we must do for this case is to calculate the volume of the can using the largest diameter:
 V = pi * ((d / 2) ^ 2) * (h)
 Where,
 h: height
 d: diameter.
 Calculating we have:
 V = pi * ((2.60 / 2) ^ 2) * (4.83) = 25.64 in ^ 3
 Then, to determine the amount of liquid in millimeters, we can use a simple rule of three:
 1 in ^ 3 ---> 16.3891 milliliters
 25.64 in ^ 3 ---> x
 Clearing x we have:
 x = ((25.64) / (1)) * (16.3891) = 420.22 mm
 answer
 The amount of liquid that has been bottled in milliliters is 420.22 mm
