Question 10 • *Integrated Math II Full
Carl is trying to determine the length of segment MN using the Pythagorean theorem. Step 1: Find the vertex of a possible right triangle. V(4, 1)Step 2: Find the leg lengths of the right triangle. NV = 7, MV = 5Step 3: Substitute the values into the Pythagorean theorem. Step 4: Solve for c. Which best describes the accuracy of Carl’s solution?
Answer
A
Carl’s work and answer are both entirely correct.B
Carl’s answer is correct, but he incorrectly labeled the leg lengths in step 2.C
Carl’s work and answer are incorrect. He choose a vertex, V, that does not make a right triangle with MN.D
Carl’s work and answer are incorrect. He substituted and solved incorrectly.
