Answer:
Option D is correct.
[tex]\overline{BC} = 122[/tex] units
Step-by-step explanation:
Using Pythagoras theorem:
[tex]\text{Hypotenuse side}^2 = \text{Opposite side}^2+ \text{Adjacent side}^2[/tex]
As per the given right angle triangle ABC diagram:
In triangle ABC; we have
Hypotenuse side = BC
Opposite side = AB = 22 units
Adjacent side =AC= 120 units
Apply the Pythagoras theorem on rt angle triangle ABC we have;
[tex]\text{BC}^2 = 22^2+120^2[/tex]
⇒[tex]\text{BC}^2 = 484+14400 = 14884[/tex]
⇒[tex]\tet{BC} = \sqrt{14884}=122[/tex] units
Therefore, the length of side BC is, 122 units
