Answer:
The mean is 18
Step-by-step explanation:
Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.
Answer: 4x^2 + 3x + 4
(x^2 + 3x^2) + (2x +x) + 3 + 1
Just turn the percentage to a decimal. 145% becomes 1.45. Then add 1.00 to 1.45. 1 + 1.45 = 2.45
Then multiply. 2.45 * 340 = 833
Basically the line is 180° in total.
If one side is 129°
then the other side is 180 - 129
which means x = 51°
