Answer:
the answer is 13.5
Step-by-step explanation:
A=105
B=4
C=7
so you just plug in using the trigonometric formula for area which in this case would be
1/2(4)(7)sin(105)
then you just type that into a graphing calculator (make sure its set to degrees) then you get 13.52 which would be 13.5 rounded.
Using the variable x for the unknown number,
20 - (x + 4) = 6
is your answer!
Hope I helped :)
To find mean/average it's fairly simple!! :)
The first thing you should do is add up the first numbers -
* 20 + 15 + 16 = 51 :)
* 16 + 19 + 17 = 52
Now divide each of the scores by the amount of numbers there is -
* 20 (1) 15 (2) 16 (3)
* 16 (1) 19 (2) 17 (3)
51 ÷ 3 = 17 (Rolanda's Average Score)
- Which # is bigger?
52 ÷ 3 = 17.3 (Jetta's Average Score)
