Respuesta :

We can solve this problem by the rule of three:

1.5 cm---------------15 cm
1.2 cm---------------  x

x=(1.2 cm*15 cm) / 1.5 cm=12 cm.

answer. a=12 cm.

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 =[tex]k=\frac{\text{ actual length of c}}{\text{length of c in figure}}[/tex]

[tex]k=\frac{15}{1.92}=7.8125[/tex]

Now, the length of side 'a' = 1.2 cm

The actual length of side 'a' [tex]k\times1.2=7.8125\times1.2=9.375\text{ cm}[/tex]
