First, subtract #color (red) ($145)# from each side of the equation to isolate the #w# term while keeping the equation balanced:
Solve: 1. sin x = 0.5623 2. cos x = 0.8963 3. tan x = -2.89 1. Calculator gives --> sin x = 0.5623 --> x = 34.22 and x = 180 - 34.22 = 145.78 deg. Extended answers: x = 34.22 + k360 deg x = 145.78 + k360 deg 2. cos x = 0.8963 --> x = +- 26.32 deg Extended answers: x = +- 26.32 + k360 deg. 3. tan x = -2.89 --> x = -70.93 and x = -70.93 + 180 = 109.09 deg Extended answers: x = 109.09 + k180 deg
Another (2015 TB 145 ) came a little beyond Moon's maximum apogee distance of 405400 km. In view of all these findings, it is reasonable to admit that the Earth is yet to clear some NEOs like the asteroid (2016 RB1) that had come as close as 40000 km to the Earth.
