2,4,6
hmm, increases by 2
an=a1+d(n-1)
a1=first term
an=nth term
d=common differnece
increases by 2 and starts with 2
a1=2
d=2
an=2+2(n-1)
15th apartment/collumn
a15=2+2(15-1)
a15=2+2(14)
a15=2+28
a15=30
30 windows
Probably the question should say , as is negative for .
In that case, recall that
Because lies in the third quadrant, we expect to also be negative, so we take the negative root above. Then
Answer:
It would be 12 as well
Step-by-step explanation:
If CD=BC then CAD=CAB.
I hope that helps. Let me know if it is right.
Complement means the other angle that will sum up to 90°
So:
x + 2x = 90°
3x = 90
x = 30°
So, it is 30° and 30 * 2°, or 60°
