Answer:

84 complete turns

Step-by-step explanation:

In order to find the number of turns that the bicycle wheel is going to take while going 792 feet, we need to find the circumference of the wheel.

C = \pi \: d = 3.14 \times 3 = 9.42 \: ft \\ no \: of \: turns =  \frac{792}{9.42}  \\  = 84.0764331 \\  = 84 \: turns

Assume that lines that appear to be tangent are tangent. O is the center of the circle. Find the value of x.
MariettaO [177]
Draw an imaginary line from the vertex of angle x to the center of the circle.
This divides the 4-sided polygon into two right triangles.  For example, the upper right triangle has an acute angle whose measure is 135 degrees / 2, or 67.5 degrees, and the another acute angle whose measure is x/2.

x/2 and 67.5 degrees are complementary angles, so x/2 + 67.5 deg = 90 deg.  Thus, x/2 = 22.5 deg, and so x = 45 deg.  (answer)
