Answer:

x=4

Step-by-step explanation:

If all the figures are similar, we'll have to shrink them at the same rate as the rest.

The ratio here is 2/5. So,

2/5 = 6.4/16

2/5 = x/10

x=4

Answer:

3.9 in (approximately 4 in)

Step-by-step explanation:

10/16 x 100 = 62.2 (represents 162.2%)

(100% is x) therefore, 100/162.2% x 6.4 = 3.9

OR

Ratio Method:

Ratio is 10/16 simplified is 5/8

Then you just multiply 5/8 x 6.4 in for corresponding triangle side x = 4
