Use cos sin and tan and looks up rules of cos sin tan and it will show you the rules and use those methods to plug into your equation
Distance from base = 305 / tan(29.5deg)
= 539 ft
25 and then add the decimals they have to be aaddd by the two decimals
D as you can see on the number line d is 1/3 of the way to -2
1 mile= 5280 feet
1/5280= 4.25/x This is a proportion.
5280 * 4.25= 22440
22440/1= 22440
4 1/4 miles= 22440 feet
Hope this helps! :D
