Using the identity sin? O + cos? O = 1, find the value of tan O, to the nearest
Novosadov [1.4K]

Answer:

<u>3.7</u>

Step-by-step explanation:

<u>Given</u>

  • sin²θ + cos²θ = 1
  • sinθ = 0.27

<u>Solving for cos</u>θ

  • cos²θ = 1 - sin²θ
  • cos²θ = 1 - (0.27)²
  • cos²θ = 0.0729

<u>Finding tan</u>θ

  • tanθ = sinθ / cosθ
  • tanθ = 0.27 / 0.0729
  • tanθ = <u>3.7</u>

<u>Verifying it lies in the range</u>

  • θ = tan⁻¹ (3.7)
  • θ = 74.88°
  • Range is : 0 < θ < π/2 [or 0 < θ < 90°]
  • It lies in the range [Verified]

suter [353]

Answer:

t = k \frac{1}{s}  \\ 2 = k. \frac{1}{60} \\ k = 120 \\ k \:  \: is \: constant \: of \: variation \\ relationship \: is  \\ t =  \frac{120}{s} . \\ when \: s \:  = 90 \\ t =  \frac{120}{90}  \\ t =  \frac{4}{3}  \\ when \: t = 2 \frac{1}{2}  \\ s =  \frac{120}{2 \frac{1}{2} }  \\ s = 48
