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

Answer:
The difference between the circumference of the tires is 12.56 inches.
Step-by-step explanation:
Given:
Diameter of old bicycle tires = 12 inch
Diameter of new bicycle tires = 16 inch
We need to find the difference in circumference of the tires.
Solution:
First we will find the circumference of Old bicycle tires.
Circumference can be calculated by π times diameter.
Circumference of Old bicycle tire =
Now we will find the circumference of new bicycle tire.
Circumference of New bicycle tire =
Now to find the difference between the circumference of the tires we will subtract Circumference of New bicycle tire from Circumference of Old bicycle tire we get;
framing in equation form we get;
difference between the circumference of the tires =
Hence The difference between the circumference of the tires is 12.56 inches.
