Approximate the unknown side x in the diagram. <br> A. 3.356<br> B. 5.222<br> C. 3.064<br> D. 4.737
Marianna [84]

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 = \frac{Opposite side}{Adjacent side}

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
