a 31 meter pole breaks and the tip touches the ground 10 meters from the base of the pole. How tall is the part of the pole that is still standing?

a suared + b squared = c squared

10 squared + b squared = (31-b)squared

To determine the height of the part of the pole that is still standing, we can subtract the distance from the tip to the ground from the total height of the pole.

Given:
Total height of the pole = 31 meters
Distance from the tip to the ground = 10 meters

To find the height of the standing part of the pole, we subtract the distance from the tip to the ground from the total height of the pole:

Height of the part of the pole that is still standing = Total height of the pole - Distance from the tip to the ground
= 31 meters - 10 meters
= 21 meters

Therefore, the part of the pole that is still standing is 21 meters tall.
