Answer 2

Problem:

We are given that there is an electrical pole with a height of 11 meters. Next to it is a building with a height of 7 meters. A cable is stretched between the pole and the building. The distance between the pole and the building is 3 meters. We need to find the length of the cable. A diagram should also be provided.

Solution:

To find the length of the cable, we can use the Pythagorean theorem. Let's call the length of the cable x. Then:

x^2 = (11-7)^2 + 3^2 x^2 = 4^2 + 3^2 x^2 = 16 + 9 x^2 = 25 x = 5 meters

Therefore, the length of the cable is 5 meters.
