Which of the following answer choices indicates the correct side lengths of the figure?

Side opposite 45° = x, hypotenuse = x √2

Side opposite 45° = x √3, hypotenuse = 2x

Side opposite 45° = 2x, hypotenuse = x √2

Side opposite 45° = x √3, hypotenuse = x √2

Which of the following answer choices reflects logical reasoning regarding the sample question?

The missing angle is 45° and missing side is 5 √2. Therefore this is a 45°,45°,90° triangle.

The missing angle is 65° and the missing side is 4. Therefore this is a 45°,45°,90° triangle.

The missing angle is 90° and the missing side is 5.

The missing angle is 55° and the missing side is x √3.

By dropping an altitude down the middle

By dividing the angles by the area

By dividing the perimeter by the area
