Sorry, by which method I meant the one you are using or the sin rule (seen above)

So which methed is more accurate?

x0.2126=x0.1584+3.1677 x0.0542=3.1677 x=58.47

a/sinA = b/sinB = c/sinC 180 - 12 = 168 180 - (12+90) = 78 180 - (9+90) = 81 81 - 78 = 3 (top corner) a/sin168 = 20/sin3 a = (20 x sin168)/sin3 a = 79.45 c/sin9 = 79.45/sin168 c = (79.45 x sin9)/sin168 c = 59.78 Correct?

A boat is some distance away from a small lighthouse. The angle of elevation from the boat is 9 degrees. If the boat moves forward 20m, the angle is now 12. Assume the lighthouse is at a rightangle to the boat. Calculate the distance from the boat to the top of the lighthouse before and after...
