4. | Which statement follows from statements (1) and (2) by the Law of Syllogism? (1) If two adjacent angles form a linear pair, then the sum of the measures of the angles is 180. (2) If the sum of the measures of two angles is 180, then the angles are supplementary. |

5. | The statements ''If Eric reads the book, he will be prepared for the exam'' and ''If Eric is prepared for the exam, he will get a passing grade'' are two conditionals. Use the Law of Syllogism to reach a logical conclusion. | |||||

If Eric prepares for the exam, then he will read the book. | If Eric reads the book, then he will get a passing grade. | |||||

no logical conclusion. | If Eric gets a passing grade, then he did prepare for the exam. | |||||
