Explanation
To obtain an average, add the numbers given and then divide by the amount of terms in the problem. This produces the mean (average). In this problem, 80 + 46 + 32 + 22 = 180 / 4 (number of terms) = 45.
\(\sqrt[3]{{64}}=? \)
Solve for x by factoring:\( {x^2} - 13x + 42 = 0\)
In the diagram is a parallelogram. What is the angle of “A” if the angle “b” is 117°?
