Find the length of the unlabeled leg of the right triangle if the hypotenuse is 13 amd bottom leg is 12

Hypotenuse is the longest side - opposite the right angle

l^2 + b^2 = H^2

l^2 = 13^2 - 12^2

l^2 = 169 - 144 - 25

l = Sqt of 25 = 5

Ok so

for a right triangle with legs legnth a and b, and hypotnuse legnth c

a^2+b^2=c^2

hypotonuse is 13

one leg is 12

other leg is?

a=12

b=?

c=13

sub and find?

12^2+?^2=13^2

144+?^2=169

minus 169 both sides

?^2=25

sqrt bot sies

?=5

the legnth is 5 units
