I got 0 as the y coordinate. Please help me solve for x
(-3.4,0)
Well, if we're looking for a point on a circle of radius 3.4 centered at the origin, and we want it to be at an angle of 180 degrees, then we can use a little bit of trigonometry to help us out.
First, let's remember that the x-coordinate on a circle is given by the formula x = r * cos(theta), and the y-coordinate is given by y = r * sin(theta), where r is the radius and theta is the angle.
Since we want our point to be at an angle of 180 degrees, we can substitute theta = 180 into these formulas and use r = 3.4 to find our coordinates.
So, x = 3.4 * cos(180) and y = 3.4 * sin(180).
Now, since cos(180) = -1 and sin(180) = 0, we can simplify these equations to x = -3.4 and y = 0.
Therefore, the coordinates of the point on the circle at 180 degrees are (-3.4, 0).
To find the x coordinate of the point at 180 degrees on a circle of radius 3.4 centered at the origin, we can use the cosine function.
The cosine of 180 degrees is -1. Therefore, the x coordinate will be -3.4.
So, the coordinates of the point at 180 degrees on the circle of radius 3.4 centered at the origin is (-3.4, 0).
To find the x-coordinate of the point located at 180 degrees on a circle with a radius of 3.4 centered at the origin, you can use trigonometry.
Since 180 degrees corresponds to the x-axis on the unit circle, the x-coordinate of the point will be equal to the radius of the circle (3.4 in this case).
Therefore, the coordinates of the point will be:
(3.4, 0)
