So in this question, we’re gonna use the sine trigonometric ratio, which equals opposite/hypotenuse.
sin32° = x (the opposite angle)/ 10 (the hypotenuse)
Then rearrange the equation to solve for x:
(10)(sin32°) = x
[Solve for sine using a calculator!]
(10)(0.529919264) = x
[Multiply]
5.299192642 = x
[Round to the nearest tenth]
x ≈ 5.3
I hope this helped!
