Answer:
The answer to your question is sin Ф = [tex]\frac{4}{5}[/tex], Number 1, four fifths
Step-by-step explanation:
Just remember that the trigonometric function sine Ф relates the opposite side and the hypotenuse.
sin Ф = [tex]\frac{Opposite side}{hypotenuse}[/tex]
From the triangle
Opposite side = 8
Hypotenuse = 10
sin Ф = [tex]\frac{8}{10}[/tex]
Simplification
sin Ф = [tex]\frac{4}{5}[/tex]
Result
sin Ф = [tex]\frac{4}{5}[/tex]
