Question

prove that tan36×tan54=1​

Answer 1

Answer:

Here's Your Answer :-

$\tan(36) \times \tan(54) = 1 \\ \\ \frac{1}{ cot(36) } \times (54) = 1 \\ \\ \frac{1}{ \cot(90 - 36) } \times \tan(54) = 1 \\ \\ \frac{1}{ \tan(54) } \times \tan(54) = 1 \\ \\ 1 = 1$

$\mathfrak{Answer\:is}$

$tan(36) × tan(54) = 1$

$\frac{cot(36)}{1} × (54) =1$

$\frac{1}{cot (90 - 36)} × tan(54) = 1$

$\frac{1}{tan(54)} × tan(54) = 1$

1=1
