The 99 percent confidence interval for the population mean is found from:
The answer is:
Label the vertices of the quadrilateral A, B, C, D. Angle C is supplementary to the angle of measure 60 degrees, so its own measure is 120 degrees.
AD and BC are parallel, as are AB and CD, so ABCD is a parallelogram. This means angle A also has measure 120 degrees. The angle adjacent to the one with measure 
, part of angle A, then has measure 
.
The three angles above the line through vertex A are supplementary, so we have
Answer:
3m²
Step-by-step explanation:
A square is quadrilateral (four sides) in which all sides are equal. Also, opposite sides are parallel to one another and all the four angles in a square are 90 degrees each.
The area of a square is given as:
Area = length * length
Given that the square has side lengths of m centimeters, therefore:
The area of each square = m cm × m cm = m² cm²
There are three rows of m squares, hence the total number of square is:
Total square = 3 rows * m squares per row = 3m squares
The total area of the square = area of each square * total number of square = m² * 3m = 3m² cm²

Answer:
20 inches per minute
Step-by-step explanation: You can find the answer by dividing the inches (120) by the minutes (6), 120/6 = 20
