Answer:
15.62
Step-by-step explanation:
[tex]a^{2} +b^2=c^2[/tex]
[tex]10^2+12^2=c^2[/tex]
[tex]100+144=c^2[/tex]
[tex]c^2=244[/tex]
[tex]\sqrt{244} =[/tex] 15.62
first option
using pythagoras theorem
a^2 + b^2 = c^2
x^2 + 10^2 = 12^2
x^2 + 100 = 144
x^2 = 144 - 100
x^2 = 44
x = [tex]\sqrt{44}[/tex]
x = 6.63
