Answer:
y ≈ 0.7
Step-by-step explanation:
locate on the x-axis, move up the vertical line until meeting the graph then the horizontal reading gives y ≈ 0.7
Answer:
y = 0.8425 or y = -0.8425
Step-by-step explanation:
All points in the Cartesian coordinate system have an x and y coordinate, defined by two perpendicular measurements.
If the point is on the unit circle, then the radius of the circle is defined to be 1 unit, and the corresponding right triangle follows the Pythagorean Theorem.
For a unit circle:
Substituting the known value for x, and simplifying...
Subtracting 0.29019769 from both sides to begin to isolate "y"...
Applying the square root property...
So, (to 4 decimal places), the y coordinate could be either 0.8425 or -0.8425.
With only the given information, either result is a valid answer.
