We can use the cosine law to find the angle between the two forces. Let's denote the angle between the 637 N force and the resultant force as θ. Then we have:
714^2 = 637^2 + 238^2 - 2 * 637 * 238 * cos(θ)
Rearranging and solving for cos(θ), we get:
cos(θ) = (637^2 + 238^2 - 714^2) / (2 * 637 * 238)
cos(θ) = -0.0130
Taking the inverse cosine, we get:
θ = 180° - acos(-0.0130)
θ = 175.8° (rounded to one decimal place)
Therefore, the angle between the two forces is approximately 175.8 degrees.
