**12.** Two poles of heights 6 m and 11 m stand on a plane ground. If the distance between the feet of the poles is 12 m, find the distance between their tops.

**Solution:**

BE = 11 m and AC = 6 m **{Given}**

DE = BE - AC = 11 - 6 = 5 m

AB = DC = 12 m

In

**Applying Pythagoras theorem, we get**

m
