Find the value 'x', if:

योग

In right ΔABC,

tan30° = `"AB"/"BC"`

⇒ `(1)/sqrt(3) = (10)/x`
⇒ x = `10sqrt(3)"cm"`.

अध्याय 27 Trigonometrical Ratios of Standard Angles
Exercise 27.2 | Q 9.1

Find the magnitude of angle A, if 2 sin A cos A - cos A - 2 sin A + 1 = 0

Solve for x : 2 cos 3x - 1 = 0

Solve the following equation for A, if `sqrt3` cot 2 A = 1

Calculate the value of A, if (sec 2A - 1) (cosec 3A - 1) = 0

Solve for x : tan² (x - 5°) = 3

Solve for x : cos² 30° + cos² x = 1

If θ = 30°, verify that: sin2θ = `(2tanθ)/(1 ++ tan^2θ)`

If `sqrt(3)`sec 2θ = 2 and θ< 90°, find the value of θ

Evaluate the following: cot20° cot40° cot45° cot50° cot70°

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