Question

Find the length of CD. Round to the nearest tenth (use distance formula)

Answer 1

3.61

Explanation:

See the attached worksheet.

Form a right triangle with the lines as drawn, in a manner that line CD becomes the hypotenuse. Then find the lengths of the two sides and use the Pythagorean Theorem to solve for CD. CD =
`√(13)` or 3.61.

Note: 13^(1/2) is
`√(13)`
