Hello
We can approach science from various angles. It may be that our aim is to solve a problem or to try to understand something. But, at the same time, what we find in it as explanatory or credible may be different if our profession is to be a trader, an importer of industrial equipment, a researcher or a teacher. Our concerns about science may differ according to the angle from which we think about it. That is to say, what is important when judging or evaluating science is different according to our relationship with it at certain times: whether we see it as producers, disseminators or consumers. Therefore, from the outset we have an area of complexity in thinking about science from our starting point.

Answer:
(15/17 = sin ∠ JLK)
(first option listed)
Explanation:
the "sin ∠ JLK" is what we can simply think of as the inside measurement of angle/corner L. (L is the letter in the middle of ∠ JLK , and if you imagine drawing a line from J to L to K, you would see that the only angle you formed both sides of is corner L)
so, we are looking for the sin of L.
(SOH CAH TOA)
we know that
sin = opposite / hypotenuse
However, we do not have the opposite value of this triangle <em>yet. </em>
-----
we can solve the length of the opposite side with the Pythagorean theorem:
a² + b² = c²
8² + b² = 17²
64 + b² = 289
- 64 - 64
b² = 225
√b² = √225
b = 15
----
so, to solve for sin L,
(sin = opposite / hypotenuse)
we should divide the opposite (15) over the hypotenuse (17)
so, 15 / 17 = sin L
(15/17 = sin ∠ JLK)
