The triangle is a right-angled triangle with a perpendicular side of 5 and a hypotenuse of 8.3.
[tex]\theta = sin^{-1}\dfrac{5}{8.3}[/tex]
as we know that sine for any angle is the ratio of its perpendicular to the hypotenuse, and trigonometry is only applicable to a right-angled triangle.
therefore,
[tex]\theta = sin^{-1}\dfrac{5}{8.3}\\\\sin \theta=\dfrac{5}{8.3}=\dfrac{Perpendicular}{Hypotenuse}\\[/tex]
Hence, the triangle is a right-angled triangle with a perpendicular side of 5 and a hypotenuse of 8.3.
