If the measure of the longest side of this triangle is 4 cm, then the measure, in cm, of the height relative to this side is: 2. (Esa 2023) In a military exercise, an Engineering Company must build a bridge to connect the parallel banks of a river. To do this, Captain Delta, the military engineer responsible for the mission, fixed a point A on the riverbank where he was, and a point B on the opposite bank, so that it was perpendicular to the riverbanks. To determine the length of the bridge from point A, Captain Delta walked 50 meters parallel to the bank to point C and measured the angle, obtaining 60°. Considering the following, mark the alternative that presents the length of the bridge that should be built for the exercise. a) 25 meters b) 42.5 meters c) 50 meters d) 85 meters e) 100 meters 3.
