Question

tan20/cot70 + tan30/cot56

Answer 1

Answer:

Step-by-step explanation:

The question is not correct. It should be Tan34° instead of Tan30.

Tan20 = Tan( 90 - 70) = Cot70 (∵ Tan(90-θ) = Cotθ)

Tan34 = Tan(90 - 56) = Cot56 (∵ Tan(90-θ) = Cotθ)

So

tan20/cot70 + tan34/cot56

= Cot70/Cot70 + Cot56/Cot56

= 1 + 1

= 2.
