Looks like 14.4 because you have to add them all together and divide by the total numbers
(20+22+10+5+15)/ 5
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
The smaller number is twelve the larger number is 69
Answer:
65 degrees.
Step-by-step explanation:
It's hard to explain, but I'll try:
The outside of the first two angles is 105 and 140. Half a whole angle is 180. So, you do
180-140=40. The inside is 40.
And then 180-105=75.
Then you add the two and subtract them from 180:
40+75= 115
180-115=65
Voila!
