In right ΔPQS,

sin30° = `"PQ"/"PS"`

⇒ `(1)/(2) = x/(100)`
⇒ x = 50m.

पाठ 27 Trigonometrical Ratios of Standard Angles
Exercise 27.2 | Q 9.5

If 2 cos (A + B) = 2 sin (A - B) = 1;
find the values of A and B.

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

Find the value of 'A', if cot 3A = 1

If A = 30°, verify that cos2θ = `(1 - tan^2 θ)/(1 + tan^2 θ)` = cos⁴θ - sin⁴θ = 2cos²θ - 1 - 2sin²θ

If θ < 90°, find the value of: sin²θ + cos²θ

Find the value 'x', if:

Find x and y, in each of the following figure:

Evaluate the following: `(sec34°)/("cosec"56°)`

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

If sin(θ - 15°) = cos(θ - 25°), find the value of θ if (θ-15°) and (θ - 25°) are acute angles.
