Given that tan θ ≈ 1.072, where 0 &lt; θ &lt; , 2 π find the values of sin θ and cos θ.
anygoal [31]

Answer:

The answer to your question is

sin Ф = 0.731 and sinФ = -0.731; cos Ф 0.682 and cos Ф = -0.682

Step-by-step explanation:

tan Ф = 1.072,  0 < Ф < 2 π,   tan Ф is positive, find the solution in the first and third quadrangle.

- tan Ф = opposite side / adjacent side

- 1.072 / 1 = opposite side / adjacent side

- opposite side = 1.072 and adjacent side = 1

  Calculate hypotenuse

  c² = a² + b²

  c² = 1.072² + 1²

  c² = 2.149

  hypotenuse = c = 1.466

First quadrangle

  sin Ф = 1.072 / 1.466 = 0.731

  cos Ф = 1 / 1.466 = 0.682

Third quadrangle

  sin Ф = -1.072 / 1.466 = -0.731

  cos Ф = -1 / 1.466 = -0.682

Anser number 6 for me so i kan get a better grade
Arlecino [84]

Answer:

Rita is left with approximately \$ 4

Step-by-step explanation:

Given:

Price for trousers= \$ 19.39

Price for shirt = \$ 27.88

Price for headscarf = \$ 8.62

Total Money she Spent = Price for trousers + Price for shirt + Price for headscarf = \$ 19.39 + \$ 27.88+ \$ 8.62 = \$55.89

Total Money she had before = \$60

∴Total Money left = Total Money she had - Total Money she spent = \$60 - \$55.89 = \$4.11

Rounding to nearest whole number ≈ \$4
