Q) In the given figure, ∆ AHK ~ ∆ ABC. If AK = 8 cm, BC = 3.2 cm and HK = 6.4 cm, then find the length of AC.
Ans:
Step 1: Since Δ AHK ~ Δ ABC (given)
Therefore, 
∴ AC = 
Step 2: It is given that AK = 8 cm, BC = 3.2 cm, HK = 6.4 cm
by substituting the given values, we get:
AC = 
= 
= 4 cm
Therefore, the length of AC is 4 cm
