Answer:
The answer to your question is x = 3.356 cm
Step-by-step explanation:
This is a right triangle so we can use the Trigonometric functions to solve this problem.
Data
Ф = 40°
Adjacent side = 4 cm
Opposite side = x
Process
1.- We must know the lenght of the opposite side so we must use the tangent to solve it.
     tangent Ф = 
2.- Solve it for Opposite side
     Opposite side = tanФ x Adjacent side
      Opposite side = tan 40° x 4
      Opposite side = 0.839 x 4
      Opposite side = 3.356
      Opposite side = x = 3.356 cm
