a^2 + b^2 = c^2
b = sqrt(c^2 - a^2)
b = sqrt(51^2 - 45^2) = sqrt(576)
b = 24 feet

the rule is a squared plus b squared equals c squared, c being the hypotheneuse. so if you call the side you don't know x, you would write out 45 squared plus x sqaured equared 51 squared. then you would subtract 45 sqaured from each side of the eqation. so you would ave 51 squared minues 45 squared equals x sqaured. which is 576 equals x sqaured. so x would be 24.

24 feet.
Hypothenus^2 - known side ^2 = unknown side ^2
So 51^2 - 45^2 = 2601 - 2025 = 576
and the square root of 576 is 24.

hypotenuse (C) = 51'
side A = 45'
a^2 + B^2 = C^2
b = (c^2 - a^2)^(1/2)
b = (2601-2025)^(1/2)
= 576^ (1/2) = 24

If a^2 + b^2 = c^2, then 45^2 + b^2 = 51^2, then 2,025 + b^2 = 2,601, then b^2 = 576, then b= 24 (approx). OR you can do your own homework.

(hypotenuse)^2 = (one side)^2 + (other side)^2
51^2 = 45^2 + x^2
x = 24 feet

a-squared, as a2,+b2=c2, so you are solving for b
where a is 45 and c is 51
b2=c2-a2
find the square root of b2

How about to do your homeworks by yourself?
A little hint: Try to solve it with Pythagoras!!
