Which of the following answer choices indicates the correct side lengths of the figure?
Side opposite 45° = x √3, hypotenuse = 2x
Side opposite 45° = x, hypotenuse = x √2
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 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.
The missing angle is 45° and missing side is 5 √2. Therefore this is a 45°,45°,90° triangle.
