notice, the first term is 9.5
from there it goes to 11.5, well, how much is it being added to get 11.5?
well 9.5 + 2, is 11.5, so it was added 2 to 9.5
then it goes from 11.5 to 13.5, namely, 11.5+2 = 13.5
and then 13.5+2 = 15.5 and so on
so, the "common difference" or the common addition value, is 2
how do you find the nth term?
well
Answer:
1) 60 and 30 degrees
2) 150 and 30 degrees
Step-by-step explanation:
(2+1)x=90
3x=90
x=30
2*30=60
1*30=30
The missing angles are 60 and 30 since they are in the 2:1 ratio
(5+1)x=180
6x=180
x=30
5*30=150
1*30=30
The missing angles are 150 and 30 since they are in the 5:1 ratio
Also, it's spelled angles not angels that's different.
