Answer:
   232°
Step-by-step explanation:
There are a couple of ways to find the desired direction. Perhaps the most straightforward is to add up the coordinates of the travel vectors.
   30∠270° +50∠210° = 30(cos(270°), sin(270°)) +50(cos(210°), sin(210°))
   = (0, -30) +(-43.301, -25) = (-43.301, -55)
Then the angle from port is ...
   arctan(-55/-43.301) ≈ 231.79° . . . . . . . 3rd quadrant angle
The bearing of the ship from port is about 232°.

<em>Comment on the problem statement</em>
The term "knot" is conventionally used to indicate a measure of speed (nautical mile per hour), not distance. It is derived from the use of a knotted rope to estimate speed. Knots on the rope were typically 47 ft 3 inches apart. As a measure of distance 30 knots is about 1417.5 feet.
 
        
             
        
        
        
B :) open circle means inequality and it needs to be at least 3 so the line has to increase, meaning the arrow is going right.
        
             
        
        
        
Answer:
your answer is 0.375
Step-by-step explanation:
 
        
             
        
        
        
360=x+x+(2x+3)+(2x+3)
we have 360=2x+2x+2x+6
360-6=6x
354=6x
x=354/6=59
x=59
        
                    
             
        
        
        
Answer:
3/4 of the area of the circle is of  squared units.
 squared units.
Step-by-step explanation:
Equation of a circle:
The equation of a circle has the following format:

In which the center is  and r is the radius.
 and r is the radius.
Area of a circle:
The area of a circle of radius r is given by:

Circle (x+2)² + (y-5)² = 64
Comparing with the standard equation, we have that:

Area of the circle:

What is 3/4 of its area?

3/4 of the area of the circle is of  squared units.
 squared units.
