There is a paint chip on the edge of a gear for a music box. it rotates to (-7, 3) during one song when represented graphically. what is the cosine value of this function?

The solution would be like this for this specific problem:

Cosθ = adjacent side/hypotenuse
c^2 = a^2 + b^2 c^2 = 3^2 + 7^2 c = sqrt(3^2 + 7^2) = ?

c^2 = a^2 + b^2 c^2 = 3^2 + 7^2 c = sqrt(3^2 + 7^2) = ?

cosθ = adjacent side/hypotenuse = − 7/√58 = −7√58/58

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

it is 10.6 according to my calculations
