Question

Write the trigonometric Ratio of complementary Angles​

Answer 1

Answer:

If the sum of two angles is one right angle or 90°, then one angle is said to be complementary of the other. Thus, 25° and 65°; θ° and (90 - θ)° are complementary to each other. →OX traces out angle ∠XOY = θ, where θ is acute. or, α = 90° - θ.

Answer 2

Answer:

The trigonometric ratios of complementary angles θ and (90∘- θ) are:

Sin (90∘- θ) = Cos θ

Cos (90∘- θ) = Sin θ

Tan (90∘- θ) = Cot θ

Cosec (90∘- θ) = Sec θ

Sec (90∘- θ) = Cosec θ

Cot (90∘- θ) = Tan θ

cos 30∘ = √32 ; sin 30∘ = 12.

tan 30∘ = 1√3 ; cosec 30∘ = 21
