(19)<br> 82/47 = 82.8/x<br> 3891.6 = 82x<br> x = 47.4585<br> x = 47.5 meters
Ghella [55]
There are two ways (of many) to do this

Method 1:
47/x = 82/73.8
47*73.8 = 82x
3468.6 = 82x
82x = 3468.6
x = 3468.6/82
x = 42.3

---------------------------------

Method 2:
47/x = 92/82.8
47*82.8 = 92x
3891.6 = 92x
92x = 3891.6
x = 3891.6/92
x = 42.3

---------------------------------

Either way, the answer is 42.3 meters
