the midpoint of 59 and 65 is 62
Sin(30°) =1/2 0.5
cos(30°) = (√3)/2
Note that the sin of an angle is equal to the cos of the complementary angle:
sin(60°) =cos(30°) = (√3)/2 since 30+60 = 90 (compl. angle)
There is a lot of seafloor spreading, and as that happens, the continents slowly begin to go a bit farther from one another.
