1.	If tan theta = 0.4 when theta lies between 0 and 360°
Answer» Answer: θ = 21.8° & 201.8° Step-by-step explanation: If tan theta=0.4,when theta lies between 0°and360°,write down the POSSIBLE values of theta and SIN theta Tanθ = Sinθ / Cosθ Cos²θ + Sin²θ = 1 => Cosθ = √(1 - Sin²θ) = Tanθ = Sinθ / √(1 - Sin²θ) = 0.4 = Sinθ / √(1 - Sin²θ) = Sinθ = 0.4 * √(1 - Sin²θ) Squaring both sides Sin²θ = 0.16 * (1 - Sin²θ) = 1.16Sin²θ = 0.16 = Sin²θ = 0.16/1.16 = Sin²θ = 0.138 = Sinθ = ± 0.371 As tanθ is +ve so if Sinθ is + ve then Cosθ should be +ve & when Sinθ is -ve then cosθ should be - ve => θ lies in 1st quadrant & 3rd Quadrant θ = 21.8° & 201.8°

1.

If tan theta = 0.4 when theta lies between 0 and 360°

Answer»

Answer:

θ = 21.8° & 201.8°

Step-by-step explanation:

If tan theta=0.4,when theta lies between 0°and360°,write down the POSSIBLE values of theta and SIN theta

Tanθ = Sinθ / Cosθ

Cos²θ + Sin²θ = 1 => Cosθ = √(1 - Sin²θ)

= Tanθ = Sinθ / √(1 - Sin²θ)

= 0.4 = Sinθ / √(1 - Sin²θ)

= Sinθ = 0.4 * √(1 - Sin²θ)

Squaring both sides

Sin²θ = 0.16 * (1 - Sin²θ)

= 1.16Sin²θ = 0.16

= Sin²θ = 0.16/1.16

= Sin²θ = 0.138

= Sinθ = ± 0.371

As tanθ is +ve so if Sinθ is + ve then Cosθ should be +ve & when Sinθ is -ve then cosθ should be - ve

=> θ lies in 1st quadrant & 3rd Quadrant

θ = 21.8° & 201.8°

y = 2x -------------------------(1)

AFTER 20 YEARS....

x + 40 = y + 20

SO , x - y = -20 ..

PUT y = 2x from (1)

x - 2x = - 20

SO, x = 20

NOW PUT x = 20 IN (1)

SO, 2 × 20 = 40

SO THE FATHER AGE IS 40 YRS
