To solve the problem step by step, we will use trigonometric ratios to find the width of the river based on the angles of depression from the bridge. ### Step 1: Understand the Problem We have a bridge that is 3 meters high above the river. The angles of depression to the banks on opposite sides of the river are 30 degrees and 45 degrees. We need to find the width of the river. ### Step 2: Draw a Diagram Draw a diagram to visualize the situation: - Let point A be the point on the bridge. ...
