Final answer:
The resultant force can be found using vector addition of the horizontal and vertical components of the given forces. The magnitude of the resultant force is approximately 52.8N and the angle it makes with the horizontal axis is approximately 61°.
Step-by-step explanation:
To find the resultant force of two forces that are not parallel, we can use vector addition. We can break down each force into its horizontal and vertical components, using trigonometry. From the given information, we can determine that the horizontal components of the forces are 80N * cos(150°) and 70N * cos(0°), and the vertical components are 80N * sin(150°) and 70N * sin(0°). Summing the horizontal and vertical components separately, we find that the resultant force is approximately 52.8N in magnitude. The angle that the resultant force makes with the horizontal axis can be found using the inverse tangent function. In this case, the angle is approximately 61°. Therefore, the resultant force is approximately 52.8N directed at an angle of 61° from the horizontal.
