Question

if triangle ABC is similar to triangle DEF and 3AB=5DE and DF=9cm find AC

Answer 1

If ABC and DEF are equal then
AB can be equal to DE
AC can be equal to DF and also BC can be equal to EF
So AB =AC
DE. DF
3=AC
5. 9 THEN CROSSMULTIPLY
9 MULTIPLY TO 3 equal to 27
On other side 5AC
Then AC= 27 / 5
AC =5. 4
