1 answer:
All the triangles are similar, so the ratio of (long leg)/(short leg) is the same. The long leg of ΔADB is .. AD = AC -DC = 20 -4 .. AD = 16 Then .. (long leg)/(short leg) = AD/DB = BD/DC .. 16/h = h/4 .. h^2 = 64 .. h = 8 Selection D is appropriate. _____ You may see this again. The altitude (h) from the right angle in a right triangle is the geometric mean of segments AD and DC. That is, .. h = √((AD)*(DC))
