Convert polar coordinates (r, q)=(5, 30) into rectangular
coordinates. Then convert rectangular coordinates
(x, y) = (3, 4) into polar coordinates. Round the results to one
decimal place.
Converting (r,
q) = (5, 30) gives (x, y) = (4.3, 2.5) and
(x, y) = (3, 4) gives (r,
q) = (5.0, 53.1).
³ Problem
Two adjacent angles measure 12
¡ 31¢ 45£ and 26¡ 54¢ 38£
respectively. Add the two angles and display the result in
DMS format. Round the results to two decimal places.
The result is 39 degrees, 26 minutes and 23 seconds.
