Answer:
Step-by-step explanation:
The resultant force of a system is defined as
[tex]F_{R}=\sqrt{F_{x}^{2}+F_{y}^{2}}[/tex]
Where
[tex]F_{R}=32[/tex]
[tex]F_{x}=19[/tex]
Replacing these values, we have
[tex]32=\sqrt{(19)^{2}+F_{y}^{2}}\\32^{2}=361+ F_{y}^{2}\\ F_{y}^{2}=1024-361\\ F_{y}=\sqrt{663} \approx 26lb[/tex]
Therefore, the right answer is A. 26 lb.
