<h3><em>The distance from the lighthouse to the boat will be given by:
</em></h3><h3><em>tan θ=opposite/adjacent
</em></h3><h3><em>θ=angle of depression=23
</em></h3><h3><em>opposite= height of the lighthouse
</em></h3><h3><em>adjacent=distance from the boat to the bottom of the light house
</em></h3><h3><em>hence
</em></h3><h3><em>tan 23=210/a
</em></h3><h3><em>thus solving for a we obtain:
</em></h3><h3><em>a=210/tan23
</em></h3><h3><em>hence
</em></h3><h3><em>a=494.73 ft</em></h3><h3><em>HOPE IT HELPS !!!</em></h3>
Answer:
I believe the answer would be 6
Step-by-step explanation:
Area = length x width
4 x 3 = 12
12/2= 6 because only half of the rectangle is shaded

The computation of the equations is illustrated below.
<h3>How to illustrate the equation?</h3>
a. x - y = 1 .... i
x + y = -9 ..... ii
Subtract the equations
-2y = 10
y = 10/-2 = -5
Since x - y = 1
x - (-5) = 1
x + 5 = 1
x = 1 - 5 = -4
b. 3x + 2y = -9
x - y = -13
Multiply equation i by 1
Multiply equation ii by 3
3x + 2y = -9
- 3x - 3y = -39
5y = 30
y = 6
Since x - y = 13
x - 6 = 13
x = 13 + 6 = 19

To me, it seems like you should make the 12 x and see what you can get for y but I could be wrong.
