Answer:
Angle ORP and Angle ORN are a linear pair
Step-by-step explanation:
The proof will entail making use of the fact that ∠ORP and ∠ORN are supplementary. Whether their description as a linear pair is a statement or a reason will depend on your approach to the proof. Apparently, here, you are calling this fact a "statement".
The second (and subsequent) line(s) of the table might be ...
2 (statement) ORP and ORN are a linear pair. (reason) OR is a common side and R is a common vertex on line PN for these angles, hence they meet the definition of a linear pair.
3 (statement) ORP and ORN are supplementary. (reason) definition of a linear pair
4 (statement) 80 + (3x+10) = 180. (reason) substitution property; supplementary angles sum to 180 degrees
5 (statement) 3x = 90. (reason) subtraction property of equality
6 (statement) x=30. (reason) division property of equality
Answer:
2630
Step-by-step explanation:
5.6*(10^6) - 340,000 / 2*(10^3)
5,600,000 - 340,000 / 2,000
5,260,000 / 2000
= 2630 or 2.63*(10^3)
75.2 is already rounded to the nearest tenth, if you meant tens it's 80
