The get the answer do as follows:
1) a^2 + b^2 = c^2
2) your a=28 & b=45
3) 28^2=784 and 45^2=2,025
4) 748+2,025= 2,773
5) now you have 2,773= c^2 [solve for c by square rooting both sides]
6) the square root of 2,773 is approximately 52.6
Answer:
C. 53
Step-by-step explanation:
a²+b²=c²
28²+45²=c²
784+2025=c²
c²=[tex]\sqrt{2809}[/tex]
c = 53
