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:31.69
Step-by-step explanation:
31.69
Letter A is the correct answer because you can obviously exit out c and d, but yo get a good phrase you might as well have some parentheses to make this work because without it, would be confusing :)
So just find the factors of 90
90=2 times 3 times 3 times 5
so the factors could be
2,3,15
2,9,5
6,3,5
10,3,3
there are 4our
Answer:
5 + - 6
Step-by-step explanation:
Note a + (- b) = a - b, thus
5 + - 6 = 5 - 6 = - 1 < 0
Thus is a counter example to the sum of 2 numbers ≥ 0
