 <span>Length of outer track = sum of length of 10 pieces = circumference of the outer circle 


if R is the Radius of outer circle then... 

Circumference of the outer track = 2pi*R 


Similarly the circumference of the inner track (with radius r) = 2pi*r 


length of each outer piece is 3.4 inch more than length of inner piece 

So total outer length is 10*3.4 =34 inches more than the inner length. 


=> Outer Circumference - Inner Circumference = 34 inches 

=> 2pi*R - 2pi*r = 34 

=> 2pi(R -r) = 34 

=> R-r = 34/2pi = 5.41 inches 

=> R-r = Width of the track = 5.41 inches</span>

Answer:

WX = 7.9

Step-by-step explanation:

By applying tangent rule (law of tan) in the given right triangle WXY.

tan(W) = \frac{\text{Opposite side}}{\text{Adjacent side}}

tan(27)° = \frac{\text{XY}}{\text{WX}}

0.509525 = \frac{4}{\text{WX}}

WX = \frac{4}{0.509525}

WX = 7.85

WX ≈ 7.9

Therefore, length of side WX is 7.9 units.
