Point P (8, 0) is on the terminal arm of an angle in standard position. The value of cos is?

Answer 1

If the angle is in standard position and if (x,y) lies on the terminal side, the value of the cosine of the angle is

x / r, where r is the distance from the point to the origin. Also, y / r is the sine of the angle.

So, if θ is the angle, then cosθ = 8/8 = 1.

Answer 2

(8, 0) does not create and angle. Therefore no trigonometric functions exist.

With only a line; I can't tell you anything.

To figure a triangle either sss; asa; or sas is needed.
