Two geometry training examples have level: "Level ?" (missing difficulty) #31
"We have a triangle △ABC and a point K on BC such that AK is an altitude of △ABC. If AC=10, BK=7, BC=13, what is the area?"
Level ?
Level 3
317
"One leg of a right triangle is 12 inches, and the measure of the angle opposite that leg is 30°. What is the hypotenuse?"
Level ?
Level 2
I believe row 258 should be classified as Level 3, as the problem requires two sequential non-trivial observations ( inferring the unlabeled segment CK = 6 and recognizing the resulting 3:4:5 Pythagorean triple ) before a standard area formula can be applied.
I believe row 317 should be classified as Level 2, as the problem requires only direct recall of the 30-60-90 triangle ratio to arrive at the answer in a single step.
