Question

S either of them correct? Explain your reasoning.

Answer 1

Hey there! :)

You have to use the Pythagorean Theorem ⇒ a² + b² = c²

a = 5
5² = 5 × 5 = 25

b = 13
13² = 13 × 13 = 169

169 + 25 = 194

√194 = 13.93

That means McKenzie is correct and Cara is wrong ; c = 13.93

Hope this helps :)
