45° and be at a vertical height of
120
120 m as shown in the diagram, what is the approximate length of the rope for the kite sail?

170
170 m
To determine the length of the rope for the kite sail, we can use the Pythagorean theorem since we know that the angle is 45° and the vertical height is 120 m. This theorem states that in a right triangle, the square of the length of the hypotenuse (in this case, the rope) is equal to the sum of the squares of the other two sides. So, we can set up the equation as (120)^2 = x^2 + x^2, where x represents the length of the rope. Solving for x, we get x ≈ 120 m. Therefore, the approximate length of the rope for the kite sail is 120 m.
