Since the side is a transversal to the parallel bases, the angles formed are supplementary. This lets you write the relation

... (3x-5)° + (5x+13)° = 180°

... 8x +8 = 180

... x = (180 -8)/8 = 21.5

The value of x is 21.5.

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet.
igomit [66]
Percentage error =\frac{error}{actual measurement}  \times 100
Here error = 16 - 15.4 = 0.6
Therefore, percentage error =\frac{0.6}{15.4}  \times 100=0.039 \times 100
=3.9%

Each cone of the hourglass has a height of 12 millimeters. The total height of the sand within the top portion of the hourglass
Ratling [72]

The solution would be like this for this specific problem:

Volume of a cylinder = pi * r^2 * h 

Volume of a cone = 1/3 * pi * r^2 * h 

Total Height = 47

Height of the cone = 12

Height of the cylinder = 35

If the top half is filled with sand, then:

volume (sand) = pi * 4^2 * 36

volume (cone) =  1/3 * pi * 4^2 * 12

Total volume = 1960.353816 cubic millimeters

353816 / (10 * pi) = 62.4 seconds.

It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.
