We apply the basic trigonometric identity and determine the sine of angle A.
Cos2A + Sin2A = 1.
Sin2A = 1 – Cos2a = 1 – 0.36 = 0.64.
SinA = 0.8.
Determine the tangent of angle A.
The tangent of an angle is the ratio of the sine of this angle to its cosine.
tgA = SinA / CosA = 0.8 / 0.6 = 8/6 = 4/3 = 1 (1/3).
Answer: The tangent of angle A is 1 (1/3).
