Exercise 27.3 | Q 2.2

If 4 cos² x = 3 and x is an acute angle;
find the value of :
(i) x
(ii) cos² x + cot² x
(iii) cos 3x (iv) sin 2x

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

If sin 3A = 1 and 0 < A < 90^°, find `tan^2A - (1)/(cos^2 "A")`

Solve for x : sin (x + 10°) = `(1)/(2)`

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

If ΔABC is a right triangle such that ∠C = 90°, ∠A = 45° and BC =7units, find ∠B, AB and AC.

Find the value 'x', if:

Evaluate the following: cos39° cos48° cos60° cosec42° cosec51°

Evaluate the following: `(3sin37°)/(cos53°) - (5"cosec"39°)/(sec51°) + (4tan23° tan37° tan67° tan53°)/(cos17° cos67° "cosec"73° "cosec"23°)`

If cos3θ = sin(θ - 34°), find the value of θ if 3θ is an acute angle.
