Answer 2

To find the sine of angle C in triangle ABC, we can use the following trigonometric relationship:

sin(C) = opposite side / hypotenuse

In this case, we have the lengths of sides AB and BC. Since the opposite side of angle C is BC and the hypotenuse is AB, we can calculate the sine of angle C as follows:

sin(C) = BC / AB

Given that AB = 7 and BC = 7√3, we can plug these values into the formula:

sin(C) = (7√3) / 7

Now, we can simplify the expression:

sin(C) = √3

So, the sine of angle C in triangle ABC is √3.
