When two anchor points are utilized at an angle of 90° to support a load, the distribution of weight on each anchor point can be determined by analyzing the forces involved. In this setup, each anchor point shares the load based on the cosine of the angle to the vertical.

For a horizontal angle of 90°, each anchor point will carry an equal share of the load combined with the forces that arise from the angle of the load applied at those points. Given that the total weight is 100 lbs, the load is evenly split, but due to the geometry of the configuration, the forces are compounded.

In this scenario, using the relationship from physics and trigonometry for weight distribution, the load at each anchor point can be calculated as 100 lbs divided by the square root of 2, which is approximately 70.7 lbs. This corresponds to the upward force generated through each 90° angle leading to a calculation of approximately 71 lbs per anchor point.

This is why the answer of 71 lbs is valid. It reflects how the forces will distribute under the specified conditions and accounted for the geometric implications of the angle on the load.
