- Question #933a2 - Socratic
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
