Provide an appropriate response.Jamie used the Pythagorean theorem to find the length of the missing side of the triangle shown.
He did the following calculations:x2 + 72 = 102?x2 = 102- 72?x2 = 51?x =
?x ? 7.1Why did Jamie not get the correct answer?
What will be an ideal response?
The triangle is not a right triangle. The Pythagorean theorem only applies to right triangles.
