Initially, the two ships and the port formed an equilateral triangle with sides of length 242424 km. When the slower ship travelled 888 km, the triangle formed by the new positions of the two ships and the port became right-angled. When the faster ship reaches the port, the distance, in km, between the other ship and the port will beCAT 2024 Slot 2ABCD is a trapezium in which AB is parallel to CD. The sides AD and BC when extended, intersect at point E. If AB = 2 cm, CD = 1 cm, and perimeter of ABCD is 6 cm, then the perimeter, in cm, of △AEB\triangle AEB△AEB isCAT 2021 Slot 3In a triangle ABC, ∠BCA=50∘\angle BCA = 50^\circ∠BCA=50∘. D and E are points on AB and AC, respectively, such that AD = DE. If F is a point on BC such that BD = DF, then ∠FDE\angle FDE∠FDE, in degrees, is equal to
