Two poles, a and b, are 12 meters apart. pole a is 5 meters high. a rope 20 meters long is tied to the top of pole a and stretches to the top of pole b. what is the height of pole b? assume that pole b is taller than pole a.

The height of the pole will be 21 m.

Step-by-step explanation:

Since we have given that

Length of pole A = 5 meters

Distance between Pole A and Pole B = 12 m

Length of rope is tied to the top of pole A and stretches to the top of pole B = 20 meters

As shown in the figure below , we can apply "Pythagorus theorem" to find the height of the topper part of triangle :

So, Length of pole B will be

Hence, the height of the pole will be 21 m.

i'm not sure i quite understand, could you provide more information?
