The angle \theta_1θ 1 theta, start subscript, 1, end subscript is located in Quadrant \text{II}IIstart text, I, I, end text, and \sin(\theta_1)=\dfrac{1}{4}sin(θ 1 )= 4 1 sine, (, theta, start subscript, 1, end subscript, ), equals, start fraction, 1, divided by, 4, end fraction . What is the value of \cos(\theta_1)cos(θ 1 )cosine, (, theta, start subscript, 1, end subscript, )?

Step-by-step explanation:

The angle is located in Quadrant II.

From trigonometry, we know that:

Now, in Quadrant II,

Therefore, the Adjacent angle to

Therefore:
