WebbAnswer (1 of 6): We know, tan (90° - θ) = cot θ. So, tan 70° = tan (90° - 20°) = cot 20°. Further we know, tan A * cot A = 1. So, tan 70° * tan 20° = cot 20° * tan 20° = 1. Also it is known, tan 90° is not defined. Therefore, tan 70° * tan 20° * … Webb11 dec. 2024 · According to the trigonometric identity, tan70 = tan (20 + 50) tan70= (tan20 + tan50) / 1-tan20 tan50.
