4 x 5 x 9 = 180
4 x 4.5 = 18
15 x 12 = 180
90 x 4 = 360
cot x = (cos x) / (sin x) cos (x - 180) = cos x cos 180 + sin x sin 180 = - cos x sin (x - 180) = sin x cos 180 - cos x sin 180 = - sin x cot (x - 180) = (cos (x - 180)) / (sin (x - 180)) = (- cos x) / (- sin x) = (cos x) / (sin x) = cot x
Suppose X*(5/4) = 180 Then X = 180*4/5 = 144
4 x 5 x 9 = 180
The factor pairs of 180 are 1 x 180, 2 x 90, 3 x 60, 4 x 45, 5 x 36, 6 x 30, 9 x 20, 10 x 18, and 12 x 15.
3 x 60 = 180 4 x 45 = 180 5 x 36 = 180 6 x 30 = 180 9 x 20 = 180 10 x 18 = 180 12 x 15 = 180
2 x 180 = 4 x 90.
Suppose the angle is x degrees. Then supplementary angle = 180 - x and compementary = 90 - x So, 180 - x = 4*(90 - x) ie 180 - x = 360 - 4x or 3x = 180 or x = 60 degrees.
Suppose the angle is x degrees. Then (180 - x) = 4*(90 - x) 180 - x = 360 - 4x 3x = 180 so x = 60 degrees.
It is 45(x- 4) or 45x - 180.
√180 = √(4 x 9 x 5) = 6√5
5 x 9 = 45 45 x (-4) = -180
4 x 4.5 = 18
It is 45(x- 4) or 45x - 180.
