Answer:

y = 24√3, or approximately 41.6

Step-by-step explanation:                                √3        36

Here the ratio 36/y = cosine of 30 degrees = ------- = ------

                                                                               2         y

Cross-multiplying yields (√3)y = 72, so y = 72/√3, or 72√3/3, or y = 24√3
