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

step-by-step explanation:

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
