Answer:
Option C. √280
Step-by-step explanation:
From the question given above, the following data were obtained
MN = 19
ML = 9
LN =?
We can obtain the value of LN by using the pythagoras theory as illustrated:
M ² = ML² + LN²
19² = 9² + LN²
361 = 81 + LN²
Collect like terms
361 – 81 = LN²
280 = LN²
Take the square root of both side
LN = √280
Therefore, the length of LN is √280
