By applying the Tan trigonometric formula, the value of the tangent for angle A is equal to: A. 3√91/91.
In order to determine the value of the tangent for <A, we would apply Pythagorean theorem:
AB² = AC² + BC²
40² = AC² + 12²
AC² = 1600 - 144
AC = √1456
AC = 4√91 in.
Now, we can determine the value of the tangent for <A by applying the Tan trigonometric formula:
TanA = Opp/Adj
TanA = BC/AC
TanA = 12/4√91
TanA = 3√91/91.
