Answer:
The conclusion is "Plane R and Plane S form a line if they intersect."
Step-by-step explanation:
Consider the provided statements.
1) If two planes intersect, their intersection is a line.
2) Plane Rand plane S intersect.
- If two points lie in a plane, then the line joining them lies in that plane.
- If two planes intersect, then their intersection is a line.
For better understanding refer the figure:
There are two planes R and S, which intersect at the line l.
Since the given two planes intersect, the using the above fact we can say that their intersection is a line.
Thus, the conclusion is "Plane R and Plane S form a line if they intersect."
Answer:
42
Step-by-step explanation:
x/3+12 = 26
Multiply everything by 3 to eliminate the fraction
x+36=78
subtract 36 on both sides
x=42
42/3=14
14+12=26
Answer:

Step-by-step explanation:
9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:


10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:



11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:

Solving for 'x' we get:



12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:




3,843,000. the number next to 2 (which is in the thousands place) is 5. so we add one and it became 3,843,000
