Answer:
[tex]63.44^{0}[/tex]
Step-by-step explanation:
Tom's resultant speed is calculated as [tex]\sqrt{1^{2}+2^{2} }[/tex]
= [tex]\sqrt{5}[/tex]
The distance tom swim is the hypotenuse of the right angle triangle.
sin = opposite/hypotenuse = [tex]\frac{1}{\sqrt{5} }[/tex] = 1/5 = 0.2
arcsin (0.2) = [tex]26.56^{0}[/tex]
upstream angle =
[tex]90^{0} - 26.56^{0}[/tex] =
[tex]63.44^{0}[/tex]
