Yes it is LCM and GCF because you are trying to a factor that they both have
Answer:

Step-by-step explanation:
First, eliminate the lowest grade (76). Now, find the average/mean of the remaining 4 test grades. To do so, add up all the test grades, then divide them by the total number of test grades:
80+84+91+95=350
350/4=87.5
Hope this helps!!
as a mixed number or improper fraction-

Angles of the parallelogram which is given in the problem are:α = 49° + 17 °= 66°
β = 180° - 66° = 114°
x - length of the longest side of the parallelogram;
Use the Sine Law:x / sin 49° = 20/ sin 17°
x / 0.7547 = 20 / 0.2924
0.2924 x = 15.094
x = 15.094 : .2924
x = 51.62 is the longest side of the parallelogram.
