Answer:
Option A.
Step-by-step explanation:
The length of the hypotenuse of a right angle 145 units.
The length of one leg of the triangle can be measured by Pythagoras theorem.
other leg = [tex]\sqrt{(Hypotenuse)^{2}-(oneleg)^{2}}[/tex]
= [tex]\sqrt{(145)^{2}-(144)^{2} }[/tex] = [tex]\sqrt{21025-20736}[/tex]
= [tex]\sqrt{289}[/tex]
Therefore, option A is the correct option because the other leg should be [tex]\sqrt{289}[/tex].
