Answer:
a = 40°
Step-by-step explanation:
I. When total angle is 180 or half of circle
Find a or missing angle by
180 = 50 + 90 + x
180 - 140 = x
x = 40º
That makes a is 40º
Hope that help :)
Answer:
this is school work
Step-by-step explanation: sorry but you gotta figure this out yourself.
but, the thing is that you should figure out the stuff inside the (these -->) then figure out the rest step by step like this, x= what then try to understand y= what, then use them to answer the problem.
and if its like this 1(4x + 5y) that mean that 9xy times 1 is your answer, this is an example.
knowing the answer is between 3 & 4 plug those as x and see what you get for answers than adjust the number accordingly
3^3+2(3) = 33 so its higher than 3
4^3 + 2(4) = 72 so it is lower than 4
try the middle so try 3.5
3.5^3 + 2(3.5) = 49.875
question states use 1 decimal place so now try 3.6
3.6^3+2(3.6) = 53.856
3.5 is closest
I think is
9 + x = 16 + 27
9 + x = 43
x = 52
Answer:
neither
geometric progression
arithmetic progression
Step-by-step explanation:
Given:
sequences:
To find: which of the given sequence forms arithmetic progression, geometric progression or neither of them
Solution:
A sequence forms an arithmetic progression if difference between terms remain same.
A sequence forms a geometric progression if ratio of the consecutive terms is same.
For :
Hence,the given sequence does not form an arithmetic progression.
Hence,the given sequence does not form a geometric progression.
So, is neither an arithmetic progression nor a geometric progression.
For :
As ratio of the consecutive terms is same, the sequence forms a geometric progression.
For :
As the difference between the consecutive terms is the same, the sequence forms an arithmetic progression.
