Answer:
Step-by-step explanation:
The correct answer is A why ??
tan(θ) = 3[tex]\sqrt{5}[/tex] /2
θ = arctan (3[tex]\sqrt{5}[/tex] /2 )
θ = 73.40
Then the question is what is the value of cos(θ)
Therefore
= cos (73.40)
= 2/7, Which is A is the correct Answer: Send Love :3
The value of cos(θ) is 2/7 in first quadrant.
Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.
Given data as :
tan(θ) = 3(√5/2)
θ = tan⁻¹3(√5/2)
θ = 73.40
To determine the value of cos(θ)
Substitute the value of θ = 73.40 in cos(θ).
⇒ cos (73.40)
⇒ 2/7 (cos(θ) is positive in quadrant I)
Hence, the value of cos(θ) is 2/7 in first quadrant.
