Question from Kerry:
The answer key for the Geometry Midterm Review #74 says the answer is square root of 80, but shouldn’t it be the square root of 52? It says (4-0) squared + (8-2)squared = 16+64, but it should be = 16+36, shouldn’t it?
Answer from Dr. Callahan:
You are correct. The original Enhanced Teacher’s Guide for Geometry (ISBN: 978-0-7167-5607-1) had the correct answer. When it was republished as Answers to Exercises for Geometry (ISBN: 978-1-61999-116-3) they changed the answer.
The correct answer is SQRT(52).
