Answer:

Step-by-step explanation:
Tan 54 = 
Where opposite = 16, Adjacent = BC
1.376 = 
BC = 16/1.376
BC = 11.62
In most cases its possible, but if the 2 of the shortest side lengths are added together and the sum is greater than the 3rd side length, than making a triangle is not possible.
let's firstly convert the mixed fractions to improper fractions, then divide.
