Exercise 27.2 | Q 9.1

If sin 3A = 1 and 0 < A < 90^°, find sin A

State for any acute angle θ whether cos θ increases or decreases as θ increases.

Solve for x : 2 cos (3x − 15°) = 1

Solve for x : cos² 30° + cos² x = 1

Find the value of 'A', if 2 cos A = 1

If sin α + cosβ = 1 and α= 90°, find the value of 'β'.

Evaluate the following: `((sin3θ - 2sin4θ))/((cos3θ - 2cos4θ))` when 2θ = 30°

The perimeter of a rhombus is 100 cm and obtuse angle of it is 120°. Find the lengths of its diagonals.

Evaluate the following: tan(78° + θ) + cosec(42° + θ) - cot(12° - θ) - sec(48° - θ)

If sec2θ = cosec3θ, find the value of θ if it is known that both 2θ and 3θ are acute angles.
