Track arc

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


Correct answer:

L =  2085 m
x =  1872.7 m

Step-by-step explanation:

L=π(18074)1801127=2085 m
x=1127sin742=1872.7 m
