Answer:
7.8
Step-by-step explanation:
They are similar since all three inside angles for each triangle would be the same.
Answer:
y=50
x=30
z=100
Step-by-step explanation:
x+20=y
2y=z
x+y+z=180
x+y+2y=180
3y+x=180
-y+x=-20
4y=200
y=50
x=30
z=100
Answer:
The closed linear form of the given sequence is 
Step-by-step explanation:
Given that the first term
and 
To find the closed linear form for the given sequence
The formula for arithmetic sequence is
(where d is the common difference)
The above equation is of the given form 
Comparing this we get d=0.75
With
and d=0.75
We can substitute these values in



Rewritting as below

Therefore 
Therefore the closed linear form of the given sequence is
