Observe the triangle ABC attached.
 Notice that the angle of depression is represented with  .
.
 Knowing that the top of a lighthouse is 260 feet above water and the ship is 270 feet offshore, you can find the value of   by using arctangent:
 by using arctangent:
 
 In this case you can identify that:
 
 Therefore, substuting values into   , you get that the angle of depression is:
, you get that the angle of depression is:

The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
        
             
        
        
        
Answer:
2.55
Step-by-step explanation:1
Convert 1121\frac{1}{2}121 to improper fraction. Use this rule: abc=ac+bca \frac{b}{c}=\frac{ac+b}{c}acb=cac+b.
34+3.3−1×2+12\frac{3}{4}+3.3-\frac{1\times 2+1}{2}43+3.3−21×2+1
2
Simplify 1×21\times 21×2 to 222.
34+3.3−2+12\frac{3}{4}+3.3-\frac{2+1}{2}43+3.3−22+1
3
Simplify 2+12+12+1 to 333.
34+3.3−32\frac{3}{4}+3.3-\frac{3}{2}43+3.3−23
