Explanation Theorem used: Pythagorean theorem: The square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. Calculation: It is given that a freighter is 5.2 km farther from a Coast guard station on a straight coast than from the closest point on the coast. Draw diagram by using above information. From Figure 1 it is observed that the hypotenuse of the right triangle is x + 5.2 . Let y be the hypotenuse of the triangle. That is, y = x + 5.2 . By using the Pythgorean theorem, y = x 2 + 8.3 2 x + 5.2 = x 2 + 8.3 2 ( x + 5.2 ) 2 = ( x 2 + 8.3 2 ) 2 x 2 + 10.4 x + 27.04 = x 2 + 68.89 . On further simplification, 10.4 x = 41.85 x = 4 Find the value of y as follows
