A boat is heading towards a lighthouse, where Riley is watching from a vertical distance of 120 feet above the water. Riley measures an angle of depression to the boat at point A to be 18 degrees . At some later time , Riley takes another measurement and finds the angle of depression to the boat (now at point B) to be 65 degrees . Find the distance from point A to point B. Round your answer to the nearest foot if necessary .

313 ft

Step-by-step explanation:

It's hard to explain because its geometry, but there will be a right triangle with angle of 72 and another with angle of 25. do tan72 * 120 - tan25 * 120

Step-by-step explanation:

The information we have about the circle is:

center:

and the radius:

the general form of the equation for a circle whose center is at is as follows:

in this case since the center is at , h and k are:

and we substitute this values, and the value of the radius into the general equation:

simplifying this expression we get:
