What is the distance between the points (3, 7) and (15, 16) on a coordinate plane?

1 answer:

7 0

Square root of (3-15)^2 +(7-16)^2
Square root of (-12)^2 + (-9)^2
Square root of 144+81
Square root of 225
The distance is 15

Answer:

The distance of ship B from the Harbor is 32.26 miles

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

$cos(x) = \frac{adjacent}{hypotenuse}$
