Answer:
i am assuming that the answer is either 3.1
The mean is found by adding the time it takes Greg each day and then diving by the number of days: 27+25+32=84.
84/3=28 min
it takes Greg 32 min on the third day
Start by putting a dot at (0,3). Then you just need to go four down and three right from that dot and put another dot. Just repeat that a couple times to make sure it is straight, and connect the dots with a line. You can also go four up and three left from the (0,3) for the other side of the axis.
The missing angle is 13.6, since we got the sides we can find the hypotenuse of 8 and 11 and that is 13.6 ||
Making the answer: 13.6
Here is my math c=a2+b2=8.2+11.2≈13.60147
To find the suum the formula is (n - 2) x 180 degrees
