Answer:
Option A
Step-by-step explanation:
[tex] \sec( \alpha ) = \frac{hypotenuse \: of \: tringle}{side \: adjacent \: to \: \alpha } [/tex]
where [tex] \ alpha [/tex] is an angle of triangle.
In the triangle given above , [tex] \ alpha = angle A [/tex]. So,
[tex] \sec(A) = \frac{10}{8} = 1.25[/tex]
