Answer:
Distance from point AA to point BB = 189.3 feet
Step-by-step explanation:
Let the distance from point AA to the base of the lighthouse be represented by x, and the distance from point BB to the base of the lighthouse be represented by y. So that;
distance from point AA to point BB = x - y
To determine the value of x, applying the required trigonometric function;
Tan θ = 
Tan 13 = 
x = 
= 441.81 feet
x = 441.8 feet
To determine the value of y;
Tan 22 = 
y = 
= 252.46
y = 252.5 feet
Thus,
distance from point AA to point BB = 441.8 - 252.5
= 189.3 feet
Cross multiply the denominators by the numerators. In other words, 12 times 3 and 7 times x (x, being our missing number).
We end up with 36 and 7x.
Divide both sides by 7.
36/7x = 5.14
x = 5.14
Hope this helps!
Answer:
Four
Step-by-step explanation:
The degree of a polynomial is the highest of the degree of the monomials with non-zero co-efficient. In this problem we are given the polynomial:
The degree of the polynomial is 4.
For a polynomial of <em>n- degree </em>we have <em>n solutions counting multiplicity</em>.
So for this four degree polynomial we would have 4 solutions. Could be real or complex depending on the equation.

Answer:
length=(3x-2)
Step-by-step explanation:
area of rectangle=length*breadth
3x^2 + 7x - 6=length * (x+3)
3x^2 +(9-2)x -6=length *(x+3)
3x^2+9x-2x-6=length*(x+3)
3x(x+3)-2(x+3)=length*(x+3)
(x+3)(3x-2)=length*(x+3)
(x+3)(3x-2)/(x+3)=length
(3x-2)=length
