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]
