Inside a toy truck, there is a gear that rotates to (3, - 8) when the steering wheel is turned to the left. What is the sine value of this function?

A. 3 square root of 73 over 73

B. negative 8 square root of 73 over 73

C. 3

D. - 8

This is the the concept of trigonometry, to get the sine value of the the function given we shall proceed as follows;

Using Pythagorean theorem, the hypotenuse of the triangle will be found as follows;

The side length will be 8 units since the y-coordinate is - 8

The side width will be 3 units since the x - coordinate is 3

c^2=a^2+b^2

c^2 = (3) ^2 + (-8) ^2

c^2=9+64

c^2=73

c=sqrt (73)

Therefore the sine value will be:

sin x=3/sqrt (73)

multiply both numerator and denominator by sqrt (73) we get:

sin x = (3√73) / 73

Therefore the answer is A]
