Answer:
The given sequence is geometric sequence
In the given pattern we have next number is 
Step-by-step explanation:
Given numbers are 64,-16,4,-1
To identify the pattern of the given numbers :
Let 
, 
,
and 
To find the next number that is 
common ratio 
Therefore the common ration is
Therefore the given sequence is geometric sequence
The nth term of the geometric sequence is 
Now find the 5th term so put n=5 , 
we have
Therefore
He would have done 10+10+10 like for each stick then + How ever many ones there were and then we would have done the same for the other set . Soorry if I'm wrong
Answer:
16=D
17=A
18=A
19=B
20=D
Step-by-step explanation:
where is the chart i cant say with out a chart
put the chart in another question and ill awwnser it because theres not enough information
Hi there there's several ways this could be proven one way us to consider the allied angle theory where two angles formed between parallel lines are supplementary which in this case can be proven by
2(45)+90=180⁰ ✔
or 3(45)+45=180⁰✔
this would not be the case if it wasn't parallel
Consequently, you can also use the alternate angle theory where you essentially extend one of the lines and you'll see two equal alternate angles
