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]
Answer:
x < 10
Step-by-step explanation:
2x-8 <12
Add 8 to each side
2x-8+8 <12+8
2x< 20
Divide by 2
2x/2 < 20/2
x < 10
Independent Variable is the lightning, while your location is the dependent. because the lightning doesn't depend on where you are to occur yet your location does for you to hear/see it
