Question

HELP PLEASE OR I WILL FAIL MY GRADE!!!!!!!!!!!!!!!!! HURRY PLEASE!!!!!!!!!!!!!!!!

Mackenzie and Cara both tried to find the missing side of the right triangle.
Mckenzie's Work Cara's Work
a2 + b2 = c2 a2 + b2 = c2
52 + 132 = c2 52 + b2 = 132
25 + 169 = c2 25 + b2 = 169
194 = c2 b2 = 144
Square root 194 equals square root c squared. Square root b squared equals square root 144.
13.93 ≈ c b ≈ 12

Is either of them correct? Explain your reasoning.

Answer 1

Mackenzie is right because she did the correct work by using the Pythagorean theorem

Explanation:

Answer 2

Mackenzie is correct...
using the pythagorean theorem, a^2 + b^2 = c^2...where c is ur hypotenuse....
a^2 + b^2 = c^2
5^2 + 13^2 = c^2
25 + 169 = c^2
194 = c^2....by taking sqrt of both sides, this eliminates the ^2
sqrt 194 = c
13.93 = c
