1.	EXAMPLE22: Two buildings of height 18 mand 13 m are built at a distance of 12 m. Findthe distance between the rooftops of the twobuildings.
Answer» Here, ED is parallel and equal to BC To find the distance between their tops, we will have to find AD Here as ED is parallel to BC, angle AED=90 According to the Pythagoras theorem,AE^2 + ED^2 = AD^2=>25+144=AD^2=>169=AD^2=>13=AD friends, there is ED\|\| BC. Now we have find AD.so the angel AED= 90°.Then According to Pythagoras theorem.,, and answer isAD=13.

Answer»

Here, ED is parallel and equal to BC To find the distance between their tops, we will have to find AD Here as ED is parallel to BC, angle AED=90

According to the Pythagoras theorem,AE^2 + ED^2 = AD^2=>25+144=AD^2=>169=AD^2=>13=AD

friends, there is ED|| BC. Now we have find AD.so the angel AED= 90°.Then According to Pythagoras theorem.,, and answer isAD=13.
