Question

Find the missing side length of a right triangle with a leg measure of 3 inches and a hypotenuse measure of 5

Answer 1

Missing side length: 4

a^2 + b^2 = c^2
a^2 + 3^2 = 5^2
a^2 + 9 = 25
a^2 = 16
a = 4

Answer 2

A=3 in
c=5 in
c^2=a^2+b^2
5^2=3^2+b^2
25=9+b^2
b^2=25-9
b^2=16
b= √16
b=4
