1. A^2 + B^2 = C^2 = 3^2 + 4^2 = C^2 = 9 + 16 = 25 Square root of 25 = 5 So, in conclusion, number 1 is equal to a)5.
2. C^2 - A^2 = B^2 = 13^2 - 12^2 = B^2 = 169 - 144 = 25 Square root of 25 = 5 So, in conclusion, number 2 is equal to a)5 just like the first question.
Glad I could help and also, can you please mark my answer as the brainliest answer? Thanks.
