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"

Answer:
Length of the flag is 190 feet and width of the flag is 80 feet.
Step-by-step explanation:
Given:
Perimeter of the flag = 540 feet
We need to find the length and width of the flag.
Let the length of flag be 'l'.
Let the width of the flag be 'w'.
Now given:
length is 110 feet greater than the width
Length of the flag
Now we know that,
Flag is in rectangular shape.
So Perimeter of rectangle is given by 2 times sum of length and width.
framing in equation form we get;
Now dividing both side by 2 we get;
Now Substituting the value of 'l' in above equation we get;
Subtracting both side by 110 we get;
Dividing both side by 2 we get;
Width = 80 feet
Length
Hence Length of the flag is 190 feet and width of the flag is 80 feet.
