Answer :

It is given in the question that,


ABC is isosceles triangle


AB = AC = 7.5 cm


BC = 9 cm


Height AD from A to BC = 6 cm


We know that,


Area of triangle = × Base × Height


Area of ABC = × BC × AD


= × 9 × 6


= 27 cm2


Area of ABC = × Base × Height


27 = × 7.5 × CE

27 × 2 = 7.5 × CE


54 = 7.5 × CE


CE =




= 7.2 cm


Hence,


The height from C to AB = CE = 7.2 cm
