Answer:CPCT stands for Corresponding Parts of Congruent Triangles which is used to compare the corresponding parts of two congruent triangles to find out the relationship between the parts of the two triangles. ... If AC≅DF, AB≅DE, and BC≅EF, then triangles ABC and DEF are congruent by the SSS postulate. I HOPE THIS HELPS
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.
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
For a unit circle:
![x^2+y^2=1^2](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D1%5E2)
Substituting the known value for x, and simplifying...
![(-0.5387)^2+y^2=(1)^2](https://tex.z-dn.net/?f=%28-0.5387%29%5E2%2By%5E2%3D%281%29%5E2)
![0.29019769+y^2=1](https://tex.z-dn.net/?f=0.29019769%2By%5E2%3D1)
Subtracting 0.29019769 from both sides to begin to isolate "y"...
![y^2=1-0.29019769](https://tex.z-dn.net/?f=y%5E2%3D1-0.29019769)
![y^2=0.70980231](https://tex.z-dn.net/?f=y%5E2%3D0.70980231)
Applying the square root property...
![\sqrt{y^2}=\pm \sqrt{0.70980231}](https://tex.z-dn.net/?f=%5Csqrt%7By%5E2%7D%3D%5Cpm%20%5Csqrt%7B0.70980231%7D)
![y=\pm 0.8424976171...](https://tex.z-dn.net/?f=y%3D%5Cpm%200.8424976171...)
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.
