In triangle JKL, the length of side JK is 12 feet, and the length of side KL is 15 feet. What is the length of side JL?

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

each side has a different length.  

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
