Answer:
x = 9
Step-by-step explanation:
We know that the hypotenuse is 15(c) and one side is 12(a or b) so we can solve by using the Pythagoras theorem which is:
[tex]a^{2} + b^{2} = c^{2}[/tex]
We know c is 15 and b is 12:
[tex]a^{2} + 144 = 225[/tex]
Let’s solve:
[tex]a^{2} = 225 - 144[/tex]
[tex]a = 9[/tex] Or [tex]x = 9[/tex]
