An angle that shares the same sine value of an angle that measures 5pi/4 radians is located where?
A. Quadrant I
B. Quadrant II
C. Quadrant IV
D. along an axis

Respuesta :

If we have an angle measuring 5π/4, that is an angle that terminates in quadrant III. Then the sine value of 5π/4 is negative since sine is negative in quadrants III and IV.

The only other quadrant we can be in to have the same sine value is quadrant IV; that's the only other place sine can be negative. 

In fact, the other angle can possibly be 7π/4 via the unit circle. That's a quadrant IV angle.

Therefore, quadrant IV is the answer.

The value of the angle that shares the same sine value of an angle that measures 5pi/4 radians is located where in the Quadrant IV.

What are the quadrants?

The quadrants are the region bounded between the x-axis and the y-axis.

Given to us

An angle that shares the same sine value as an angle that measures 5pi/4 radians.

We know that the value  [tex]Sin(\frac{5\pi}{4})[/tex] is negative and, the angle lies in the third quadrat.

Let the angle that is needed be θ.

[tex]Sin(\frac{5\pi}{4}) = Sin(\theta)\\\\\\\theta = -\dfrac{\pi}{4}[/tex]

As the value of θ is negative(π/4), therefore, the angle is measured from the positive x-axis, and it lies in the fourth quadrant.

Hence, the value of the angle that shares the same sine value of an angle that measures 5pi/4 radians is located where in the Quadrant IV.
