Data

angle = Ф = 78°

Opposite side = 12 ft

Adjacent side = ?

To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.

tan Ф = Opposite side / Adjacent side

- Solve for Adjacent side

Adjacent side = Opposite side / tanФ

-Substitution

Adjacent side = 12 / tan 78

-Simplification

Adjacent side = 12 / 4.7

-Result

Adjacent side = 2.55 ≈ 2.6 ft
