Answer:
Step-by-step explanation:
cos(20°) = (14/2)/x
x = 7/cos(20°) ≈ 7.45
The shape shown is a cone and the cones perpendicular cross section is a triangle.
If you need the parallel cross section then it will be a circle.
The answer is A.

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
