Problem Num : 21 Type: Understanding Topic:Trigonometry  Theme:None Adjustment# : 0 Difficulty: 2
Category	Trigonometric ratio
Analysis	I want you to ask if this is possible to get an answer or not. For instance, the ratio BC/AC is fixed. However, the length of BC and AC can be changed.
Solution/Hint	Area of a triangle is decided by the base and height. We also know the tan ratio is related to the base and height. Tan 38= BC/AC and 1/2 AC*BC =15
