The equation can be used to solve for the measure of angle ABC is given in option (A).
Since the image of the
is missing, so i attached the same image as asked in the question.
Now according to the figure,
is a right angled triangle, right angled at C, so the hypotenuse will be Side AB.
We have to calculate the value of
.
By trigonometric ratios we know that,

Now for
perpendicular is AC and base is BC, also
will be
.( see the attached figure )
So,

Since AC is 2.4 and BC is 10.
Now,

Thus the correct option is (A).
