Answer:
6.63
Step-by-step explanation:
Since you are using a right triangle, you are going to be doing the pythagorean theorem. [tex]a^{2} +b^{2} =c^{2}[/tex] where a and b are the legs and c is the slanted side/hypotunse. Let plug it in.
[tex]a^{2} +10^{2} =12^{2}[/tex]
[tex]a^{2}[/tex]+100=144
[tex]a^{2}[/tex]=44
sqr root of 44 is [tex]2\sqrt{11}[/tex] which is about 6.63
