Question

IN LMN, THE MEASURE OF N=90, NM=5 ML=13 LN=12 WHAT RATIO REPRESENTS THE COSINE OF L

Answer 1

cos(L) = 12/13

Explanation:

The hypotenuse of the triangle is LM = 13. The side adjacent to angle L is LN = 12. (It has L in the name.) The cosine is the ratio of the adjacent side to the hypotenuse:

Cos = Adjacent/Hypotenuse

cos(L) = LN/LM

cos(L) = 12/13
