Answer:
85 feet
Explanation:
To find the distance traveled by the laser pointer's beam, we can use the Pythagorean theorem. The laser beam forms a right triangle with the tower as one side and the distance traveled as the hypotenuse.
Let's denote the distance traveled by the laser beam as x. We can set up the following equation using the Pythagorean theorem:
x^2 = 40^2 + 75^2
Simplifying this equation:
x^2 = 1600 + 5625
x^2 = 7225
Taking the square root of both sides:
x = √7225
x = 85
Therefore, the laser pointer's beam has traveled approximately 85 feet.
