Disregard the sign. Find the mean (add the numbers, and divide by the amount of numbers there are)
2 + 12 = 14/2 = 7
Add 7 (if you are going by -2), if you are starting from 12, subtract 7
-2 + 7 = 5
5 is your midpoint.
hope this helps
The equation is: (Note: Let the two numbers be x and y)
(x + y)/2 = midpoint

Answer:
Step-by-step explanation:
because <u>c</u> is shorter than<u> a</u> we know C is a smaller angle than A
so the first choice is out.
use the law of cosines to find b
= 
=1681+400-1326.787871
= 754.21219
b= 
b= 27.46292
so the last choice looks good
<u>exact form:</u>
w= 74/45
<u>decimal form:</u>
w= 1.64
<u>mixed number:</u>
w= 1 29/45
brainliest would be appreciated :)
