Answer:
B.35
Step-by-step explanation:
The sequence is
14, ,56,....
14 , x , 56
Think of it as 14 + d = x
x+ d = 56
d is the common difference
We now have 2 equations and 2 unknowns
Substitute the first equation in for x into the second equation
x+d =56
(14+d) +d = 56
Combine like terms
14 + 2d = 56
Subtract 14 from each side
14-14 + 2d = 56-14
2d = 42
Divide by 2
2d/2 =42/2
d = 21
The common difference is 21
Now we can find x
14 + d = x
14+ 21 = x
35 =x
The unknown term is 35
301,931
^ This is the 100,000 place.
We round down because the number next to it is 0.
So we round do 300,000
First angle to the right inside the triangle can be 60
Other angle inside the triangle can be 40
The upper angle outside the triangle 80
The last angle 100
<span>I think the answers to number 1 is 0, 36, 72, 108, 144, 180, 216, 252, 288, and 324 degrees
that might be wrong though
