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
1+3x /4= 5/2
1+3x = 5*4/2
1+3x =10
3x =9
x = 3
Formula for the circumference:
C = π d
Use the estimate of 3.14 for π: 9.42 = 3.14 d
Divide both sides by 3.14: d = 9.42 / 3.14 They have very conveniently given you a round number: d = 3 so your answer is A
It would be -7/9
please can i have a brainliest
