Answer:
8² = 4² + 5² - 2(4)(5) cos(P)
which is the third option
Explanation:
The general rule of cosine is:
a² = b² + c² - 2bc*cos(A)
In our triangle:
a is substituted by p = 8 cm
b is substituted by n = 4 cm
c is substituted by m = 5 cm
A is substituted by P which we want to find
Replace the variables in the general equation with the givens as follows:
p² = n² + m² - 2mn*cos(P)
8² = 4² + 5² - 2(4)(5) cos(P)
Hope this helps :)

Answer:
there will be 300 6th graders
Step-by-step explanation:
Divide 200 by 2 to find 1/5 of the school.
In the following data set, what is the range? 3, 7, 8, 4, 4, 5, 9, 10, 6, 2
OleMash [197]
To find range tou must order the numbers so they are least to greatest. Then you subtract the smallest value from the greatest value.
2,3,4,4,5,6,7,8,9,10
10-2=8
Range=8
When x=2
20-6 = 14
when x=3
20-9 = 11
the answer is x=2 will give you the larger value
