Exercise 27.1 | Q 4.6

If 2 cos 2A = `sqrt3` and A is acute,
find:
(i) A
(ii) sin 3A
(iii) sin² (75° - A) + cos² (45° +A)

In ΔABC, ∠B = 90° , AB = y units, BC = `(sqrt3)` units, AC = 2 units and angle A = x°, find:

Calculate the value of A, if cos 3A. (2 sin 2A - 1) = 0

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

Solve for 'θ': `sec(θ/2 + 10°) = (2)/sqrt(3)`

In a rectangle ABCD, AB = 20cm, ∠BAC = 60°, calculate side BC and diagonals AC and BD.

Find the value of 'x' in each of the following:

Find the length of AD. Given: ∠ABC = 60°, ∠DBC = 45° and BC = 24 cm.

Evaluate the following: `(sin62°)/(cos28°)`

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