Answer:
[tex] {c}^{2} = 42 + 122 \\ {c}^{2} = 164 \\ c = \sqrt{164} \\ c = 12.80[/tex]
C = 82
Step-by-step explanation:
first do 42 + 122 = 164
then you take the 2 from c2 and use it to divide 164 ÷ 2 = 82
and c2 means c × 2 so you take 82 and multiply it by 2 which will check if your division is right
82 × 2 = 164
so c = 82
