Step-by-step explanation:
We will be using the trigonometric ratios of complementary angles to solve the given question.
tan (90° - θ) = cot θ
Given that:
tan 2A = cot (A - 18°) ….(i)
But tan 2A = cot (90° - 2A)
By substituting this in equation (i) we get:
cot (90° - 2A) = cot (A - 18°)
90° - 2A = A - 18°
3A = 108°
A = 108°/3
A = 36°
