    Match the column:
    Column I Column II
    1. \[\frac{\text{Side opposite to angle }\theta }{\text{Hypotenuse}}\] A. \[\tan \theta \]
    2. \[\frac{\text{Side adjacent to angle }\theta }{\text{Hypotenuse}}\] B. \[\sin \theta \]
    3. \[\frac{\text{Side opposite to angle }\theta }{\text{Side adjacent to angle }\theta }\] C. \[\sin \theta \]
        D. \[\sec \theta \]
     

    A) 1-A, 2-C, 3-B

    B) 1-B, 2-C, 3-A

    C) 1-B, 2-C, 3-D

    D) 1-D, 2-B, 3-A

    Correct Answer: B

    Solution :

    [b] \[\frac{\text{Side opposite to angle }\theta }{\text{Hypotenuse}}=\sin \theta \]
    \[\frac{\text{Side adjacent to angle }\theta }{\text{Hypotenuse}}=\cos \theta \]
    \[\frac{\text{Side opposite to angle}\theta }{\text{Side adjacent to angle}\theta }=\tan \theta \]
