Question

4)The sine function is defined as the ratio of the magnitude of the opposite side of an angle to the magnitude of the hypotenuse of a triangle. The order pair, (-10, -9), are measured from the origin. What is the sin??

5) The sine function is defined as the ratio of the magnitude of the opposite side of an angle to the magnitude of the hypotenuse of a triangle. What is the sine function of the angle given (-8, -7)

6) The sine function is defined as the ratio of the magnitude of the opposite side of an angle to the magnitude of the hypotenuse of a triangle. The order pair, (-5, -5), are measured from the origin. What is the sin??

7) The sine function is defined as the ratio of the magnitude of the opposite side of an angle to the magnitude of the hypotenuse of a triangle. The order pair, (4, -3), are measured from the origin. What is the sin??

8) The sine function is defined as the ratio of the magnitude of the opposite side of an angle to the magnitude of the hypotenuse of a triangle. The order pair, (9, -4), are measured from the origin. What is the sin??

Explanation / Answer

4] sin theta = -9/sqrt(10^2+9^2) = -0.669

5] sin theta = -7/sqrt(7^2+8^2) =-0.6585

6] sin theta = -5/sqrt(5^2+5^2) = -0.707

7]sin theta = -3/sqrt(3^2+4^2) = -0.6

8] sin theta = -4/sqrt(9^2+4^2) = -0.406
