Answer:
16
Step-by-step explanation:
By applying the Pythagoras theorem we get,
20*20 - 12*12 = c*c
256=c*c
c= [tex]\sqrt{256}[/tex]
c=16
Answer:
16
Step-by-step explanation:
We have to use the pythagorean theorem here
a^2+b^2=c^2
12^2+b^2=20^2
144+b^2=400
b^2=256
[tex]\sqrt{b^2}=\sqrt{256}[/tex]
[tex]b=16[/tex]
