Answer:
130
Step-by-step explanation:
For this problem, we will apply the Pythagorean theorem which states:
a^2+b^2=c^2
*where a and b are short sides in the right triangle and c is the longest side or hypotenuse*
We are given that:
a=50
b=120
We can find the longest side c as:
a^2+b^2=c^2
50^2 +120^2=c^2
2500+14400=c^2
16900=c^2
c=130
We can conclude the length of the longest side is 130.
