Answer :
so pythagorean theorem
a^2+b^2=c^2
a and b are legs
c=hypotonuse
legs=12 and 16
subsitute
12^2+16^2=c^2
144+216=c^2
400=c^2
squareo root both sides
20=c
hypotonuse=20 cm
a^2+b^2=c^2
a and b are legs
c=hypotonuse
legs=12 and 16
subsitute
12^2+16^2=c^2
144+216=c^2
400=c^2
squareo root both sides
20=c
hypotonuse=20 cm
