Track arc

Two straight tracks are at an angle 74°. They will join with a circular arc with a radius r=1127 m. How long will the arc be connecting these lines (L)? How far is the arc's center point from track crossings (x)?

Correct answer:

L =  2085 m
x =  1872.7 m

Step-by-step explanation:

L=180π(18074)1127=2085 m
x=sin2741127=1872.7 m
