Determine the y component of reaction at a using scalar notation. express your answer to three significant figures and include the appropriate units.

In order to compute the y-component of a vector, we simply use the formula:

Fy = F*sin (∅)

Where ∅ is the angle of the vector measured from the positive x-axis and F is the magnitude of the vector.

Similarly, the x-component is calculated by substituting sin (∅) with cos (∅)
