The answer is supplementary angles, hopefully that helps.
Answer:
Step-by-step explanation:
Here, we can use an angle rule.
We see that angles ° and 130° are under a sort of F shape, where lines m and n are the horizontal parts of the letter and where the diagonal line is the vertical part of the letter.
This means we can use the rule:
Corresponding angles are equal.
This means that:
We can now use this equation we have formed to solve for :
Therefore, our final answer is .
The answer is 9. you start with 1+2 in the parenthesis and then divide 6 by 2. that gives you 3x3 which is 9
Answer:Alkanes: CnH2n+2
n=8 --> C8H18. So it is 18 atoms
Step-by-step explanation:
375+147=530 you can round 375 up to 380 147 would be rounded to 150 and add 380+150=530.
