Here’s the step-by-step answer!
Answer:
a <
Step-by-step explanation:
Given
a - 15 > - 40 - 6 + 3a ← simplify right side
a - 15 > - 46 + 3a ( subtract a from both sides )
- 15 > - 46 + 2a ( add 46 to both sides )
31 > 2a ( divide both sides by 2 )
> a ⇒ a <
Answer:
No
Step-by-step explanation:
The change in the sequence is not consistent therefore it cannot be an arithmetic sequence.
Every triangles 3 angles will always add up to 180 degrees
The reason this is true in your problem is because of the corresponding angles and supplementary angles.
