Trigonometric Ratios Assignment
Consider △LNM.

Which statements are true for triangle LNM? Check all that apply.

The side opposite ∠L is NM.
The side opposite ∠N is ML.
The hypotenuse is NM.
The hypotenuse is LN.
The side adjacent ∠L is NM.
The side adjacent ∠N is ML. - CORRECT ANSWER-The side opposite ∠L is NM
The side opposite ∠N is ML
The hypotenuse is LN.
