Answer: 9.375 cm
Step-by-step explanation:
From the given picture, it can be seen that the measure of side 'c' in triangle = 1.92 cm
The actual length of 'c' in the triangle = 15 cm.
The scale factor =\(k=\frac{\text{ actual length of c}}{\text{length of c in figure}}\)
\(k=\frac{15}{1.92}=7.8125\)
Now, the length of side 'a' = 1.2 cm
The actual length of side 'a' \(k\times1.2=7.8125\times1.2=9.375\text{ cm}\)
