ANSWER
EXPLANATION
We want to solve
where
We reciprocate both sides of this trigonometric equation to obtain:
We take arctangent of both sides to get;
This is the principal solution.
The tangent ratio is also positive in the third quadrant.
The solution in the third quadrant is
Perform the indicated division ... divide the numerator by the denominator.
The quotient is the decimal form of the ratio.
A(x1, y1), B (x2,y2)
d=V(y2-y1)^2+(x2-x1)^2
d^2= (1-4)^2+[5-(-2)]^2=(-3)^2+ (5+2)^2=9+49=58
d=V58
The control group and the experimental groups are not comparable. They are selected from different districts.
Answer:
80 feet
Step-by-step explanation:
L=4w following by the increase or 2
2(L-10) + 2(W+2) = 80
