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
x=4
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
20
