Answer:
L=W+X X=2 feet, W=width, L=length
if you were to solve it then you would get L=8
Step-by-step explanation:
Answer:
are zeroes of given quadratic equation.
Step-by-step explanation:
We have been a quadratic equation:

We need to find the zeroes of quadratic equation
We have a formula to find zeroes of a quadratic equation:

General form of quadratic equation is 
On comparing general equation with b given equation we get
a=2,b=-10,c=-3
On substituting the values in formula we get


Now substituting D in
we get




Therefore, 
Notice the picture below
so.... the angle of depression, is above in dashed lines.... however, the angle of depression, is identical to the angle of elevation from the water, since, both angles are "alternate interior" angles
now, using the 45-45-90 rule, then we know the swimmer is 90 feet from the lighthouse, then just use the tangent ratio to get "x"
The answer is yes. The triangles are congruent.
I measured them with a ruler and they are the same length.
Hope this helped! c:
