Answer:
B
Step-by-step explanation:
We can use the law of cosinse:
= 
− 2ab cos(C)
Suppose the two sides are a and b, and the angle betweent them is C.
= 
− 2*3*4 cos(60)
We can simplify this to get =25-12=13

Answer:
75%
Step-by-step explanation:
divide 14/56 and you should get a decimal:
.25
then subtract that number by 1
=.75= 75%
I think 169
Reason just add
Answer:
50
Step-by-step explanation:
a triangle's sum of all angles is 180 degrees
so a+b+c=180
we know c=80
and a=b
so that'll be
2y+80=180
subtract 80 from each side
2y=100
divide by 2
y=50
Answer: The mean is 27.
Step-by-step explanation: You add up all of the numbers and divide the sum by the amount of numbers you have.
