Question

Tg10 tg20 tg30 tg40 tg50 tg60 tg70 tg80=1

Answer 1

tg10*tg20*tg30*tg40*tg50*tg60*tg70*tg80=[tg10*tg80]*[tg20*tg70*][tg30*tg60] [tg40*tg50]=[tg10*ctg10]*[tg20*ctg20*][tg30*ctg30] [tg40*ctg40]=1·1·1·1=1

Answer 2

It seems like you're asking for the value of the trigonometric function tangent (tg) for various angles. However, the trigonometric functions, including tangent, do not evaluate to a single constant value for all angles. Instead, they give different values depending on the angle in degrees or radians.

The tangent function (tg) is defined as the ratio of the opposite side to the adjacent side of a right-angled triangle. Here are the tangent values for the angles you provided:

tg(10°) ≈ 0.176 tg(20°) ≈ 0.364 tg(30°) ≈ 0.577 tg(40°) ≈ 0.839 tg(50°) ≈ 1.191 tg(60°) ≈ 1.732 tg(70°) ≈ 2.747 tg(80°) ≈ 5.671

Please note that these values are rounded to three decimal places. If you meant something else by your question, please provide more context or clarify your inquiry.
