If two of the angles of a parallelogram are acute, then the other two angles will be obtuse. Since a parallelogram contains two pairs of parallel sides, both of the acute angles and both of the obtuse angles respectively will measure the same.
Geometry was documented by the Sumerian civilization around 5,000 years ago; it was used by them in setting out temples (look up Gilgamesh). The Egyptians also studied and applied a sophisticated knowledge of geometry. In building Stonehenge, around 2,500 BC Neolithic surveyors also used survey methods based on geometric principals.
It is a plane shape bounded by four straight lines.
The volume of any prism is its cross-sectional area times its length. For a rectangular prism (a cuboid), the cross-sectional area is that of a rectangle, ie width times height. So the Volume of is Rectangular Prism is: Length x Width x Height= x^3
Length= 15 (inches)
Width= 35 (inches)
Height= 40 (inches)
(15) x (35) x (40) = 21,000^3
To make your answer into:
Gallons: (x^3) Ã· 231= (gallons)
example: (21,000) Ã· 231= 90.90 gallons.
Liters: (x^3) Ã· 61= (liters)
example: (21,000) Ã· 61= 344.26 gallons.
Cup: (x^3) Ã· 14.4= (cups)
example: (21,000) Ã· 14.4= 1458.3 Cups
Trigonometry is a type of math
once you know math you can do anything!
Think of one job that DOESN'T include math.
Some Jobs like being a scientist or a mathematician include trigonometry
