Answer:

a = 12

Step-by-step explanation:

Based on the Pythagoras theorem...

[tex]c^{2} = a^{2} + b^{2}[/tex]

(where c is the hypotenuse, and a and b are the legs of the right angle triangle)

Therefore we can rewrite it as...

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]15^{2} = a^{2} + 9^{2}[/tex]

[tex]225 = a^{2} + 81[/tex]

[tex]a^{2} = 225 - 81\\a^{2} = 144\\a=\sqrt{144} \\a = 12[/tex]
