Answer:

Length of side JL = 9ft

Step-by-step explanation:

Triangle JKL is a right angle triangle where side kl = hypotenuse= 15ft

And side jk = opposite= 12 ft

We are looking for side JL = adjacent

According to Pythagoras theorem

A² = B² + C²

15² = 12² + C²

225= 144 + C²

225-144 = C²

81= C²

9 = C

Length of side JL = 9ft

<u>Answer:</u>

BC = 18 cm

<u>Step-by-step explanation:</u>

As we can see from the diagram:

AB + BC + CD = AD

⇒ 10 cm + BC + 11 cm = 39 cm

⇒ BC + 21 cm = 39 cm

⇒ BC = 39 cm - 21 cm

⇒ BC = 18 cm
