The correct answer to this question is " 7 times square root of 74 over 74."

First, we need to get for the "r."

r^2 = (-5) ^2 + 7^2

r^2 = 25 + 49

r^2 = 74

r = square root of 74

Then, after that, we need to formulate the equation of a sin:

sin x = 7 / r

sin x = 7 / sqrt (74)

sin x = 7 * sqrt (74) / 74
