Question

if cos 70° =0.342,give another angle whose cosine is 0.342

Answer 1

cos x=cos (360-x)
other angle =360-70=290

Answer 2

360-70=290***

Answer 3

cos 70° = 0.342

To find another angle whose cosine is 0.342, we can use the inverse cosine function (cos⁻¹) on both sides of the equation:

cos⁻¹(cos 70°) = cos⁻¹(0.342)

70° = 70.53° (rounded to two decimal places)

Therefore, another angle whose cosine is 0.342 is approximately 70.53°.

Answer 4

Another angle is \[-70º\]
