Answer:
c = 12.7
Step-by-step explanation:
this is an example of the pythagorean theorem. [tex]a^{2} +b^{2} =c^{2}[/tex]
first you square a and b [tex]9^{2} =81[/tex]
then you add a and b [tex]81+81=162[/tex]
finally you find the square root of 162 and round it to the nearest 10th
√162= 12.7279 rounded to the nearest 10th 12.7
