3. Tyra is calculating the distance from town A to town C. She is given that the distance from town A to town B is 120 miles, that the distance from town B to town C is 230 miles, that town B is due south of town A, and that town C is due east of town B. She calculates that the distance from town A to town C is 259.4224 miles. Should Tyra leave her answer like that? Why or why not? If not, what answer should she give? Explain. (You may assume that Tyra has calculated correctly.) Beckmann, Sybilla. Mathematics for Elementary Teachers with Activities, (p. 513). Pearson Education. Kindle Edition.
