Best ResponseYou've already chosen the best response.0first thing i see is just to set up 2 pythagorean theorems, and solve for x and y

Best ResponseYou've already chosen the best response.0since both have a right angle and the same marked angle, so the third angle is the same

Best ResponseYou've already chosen the best response.2In a right triangle, if an altitude is drawn to the hypotenuse, then all three triangles are similar. This is the situation with this problem. Start with triangle ABC. Since angle ABC is a right angle, triangle ABC is a right triangle. Segment BD is the altitude of triangle ABC drawn to the hypotenuse of triangle ABC. That means that triangles ABC, ADB, and BDC are similar triangles. Once you know the triangles are similar, then the lengths of corresponding sides are proportional, so you can write these two proportions: \(\dfrac{AB}{BC} = \dfrac{AD}{BD} \) and \(\dfrac{AD}{BD} = \dfrac{BD}{DC} \) Replacing all segments by their given lengths, x, and y, you get: \(\dfrac{5}{y} = \dfrac{4}{3} \) and \(\dfrac{4}{3} = \dfrac{3}{x} \) \(4y = 15\) \(4x = 9\) \(y = \dfrac{15}{4} = 3.75\) \(x = \dfrac{9}{4} = 2.25\)
