Hi there!
Since we know all about parallel lines and their properties, we know that the angle opposite 2,530 is equal to 15 degrees. Then, to find x, we can use trigonometry. Specifically, sine. I have attached an image with trigonometry functions to help you.
WORK:
sin (15) = 2530/x
x * sin(15) = 2530
x = 2530/sin(15)
x = 3890.5848207
nearest tenth of a mile = 0.7 miles
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
