BTangent AC = 16Tangent DC = 4Tangent EF = 7Find the Perimeter of Triangle ACE

Answer»

given, AC(AB+BC)=16DC=4EF =7now, we know tangent drwan from point are equal. then, EF=ED. ........(I)

DC=BC. ......(ii) AB=AF. .......(iii) so, Perimeter of triangle =ED+DC+BC+AB+AF+FE=(ED+DC)+(BC+AB)+(AF+FE)=2DC+AC+2EF=2*4+16+2*7=8+16+14=28

28 is the correct answer of the given question
