Answer:
The wheel completed a total of 212 turns.
Step-by-step explanation:
A wheel has a circular form, therefore its length is given by the following formula:
Where radius is half the diameter. Applying the data from the problem to calculate the length of the wheel gives us:
Since the engine traveled a distance of 1000 metres and each turn of the wheel has 4.7124 metres, in order to calculate the number of turns the wheel made in that course we need to divide both numbers as shown below:
The wheel completed a total of 212 turns.
Answer: 3
To check:
2 * 3 = 6
Hey there,
Length = 4x
Width = 3x
Perimeter = 112 inches
4x + 3x + 4x + 3x = 112 inches
14x = 112 inches
x = 112 inches / 14
= 8 inches
Length = 8 inches x 4
= 32 inches
Width = 8 inches x 3
= 24 inches
Hope this helps :))

So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
