Use the diagram to the right to answer 5-8. 5. How many planes appear in the figure?
6. Name four coplanar points.
7. Name a point non-coplanar to plane Z.
8. Name the intersection of plane JPS and plane Z.

5. There are 5 planes in the figre

6. Four coplanar points are M, L, J, and K

7. A non-coplanar point to the plane Z is the point Q

8. The intersection of plane JPS and plane Z is the line JM

Step-by-step explanation:

5. The planes are;

a) PSR, b) QRK, c) PQJ, d) JPS, and e) plane Z, therefore, there are a  total of 5 planes in the figure

6. Four coplanar points on the plane Z are M, L, J, and K

7. A point non-coplanar to plane Z is the point Q on plane PSQ

8. The intersection of the plane JPS and the plane Z is the line JM.

step-by-step explanation:

it's 15

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
