The spokes of a bicycle wheel form 10 congruent central angles. The diameter of the circle formed by the outer edge of the wheel

Yuki888 [10]

Answer:

$5.6$ inches.

Step-by-step explanation:

The length of the outer edge of the wheel between two consecutive spokes is given by;

$l=d\sin(\frac{\theta}{2} )$

where d=18 inches.

and

$\theta=\frac{360\degree}{10}=36\degree$ is the central angle.

We substitute the values to obtain;

$l=18\sin(\frac{36\degree}{2})$

$l=18\sin(18\degree)$

$l=5.562305899$

$l=5.6$ inches to the nearest tenth.

10x - 20 = 7x + 4
Move the terms
3x = 24
x= 8
Sub back in to find the value:

torisob [31]

No the answer is not always postive. For example. If you had -50 and subtracted -30 you would have -20.
