If you sketch the path of the boat, you will form a right triangle towards the port. The distance from the port to the present position is the hypotenuse since it is opposite from the right angle formed by the 12 miles north and 5 miles east movement. Since it is a right triangle, use the Pythagorean Theorem to solve the hypotenuse.
Solution:
h² = o² + a²
h² = 12² + 5²
h² = 144 + 25
h² = 169
√h² = √169
h= 13
The present distance of the boat from the port is 13 miles.
        
             
        
        
        
Answer:
13.13
Step-by-step explanation:
5.25 x 100/40 is 13.125 which rounds up to 13.13
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
So we have: 

Multiply both sides by 11: 

The right side cancels: 

Multiply the left: 

Thus, the value of q is 33. 
 
        
                    
             
        
        
        
height = tan(11) x 210
height = 40.81 yards
 rounded to nearest tenth = 40.8 yards
