Answer to Practice Problem #1
a(to the power of 2) + b(to the power of 2) = c(to the power of 2)
21(to the power of 2) + 72(to the power of 2) = c(to the power of 2)
441 + 5184 = 5625
5625 (square rooted) = 75
c = 75
Answer to Practice Problem #2
a (to the power of 2) + b (to the power of 2)= C(to the power of 2)
13( to the power of 2) + b(to the power of 2)= 12 (to the power of 2)
169 - 144= 25
25 (square rooted)= 5
b=5
21(to the power of 2) + 72(to the power of 2) = c(to the power of 2)
441 + 5184 = 5625
5625 (square rooted) = 75
c = 75
