Answer:

m+n=23

Step-by-step explanation:

the modes m and n have to be data points more than 1 time, but equal

if there are 7 data points, then there are 4 unknown left/2 2 each

(2m-3+m+12+3n+2+m+m+n+n)/7=18

(3m+9+3n+2+m+m+n+n)/7=18

(5m+5n+11)/7=18

(5/7)*m+(5/7)*n+11/7=126/7

(5/7)*m+(5/7)*n=115/7

5m+5n=115

m+n=115/5

m+n=23

Answer:

49 degrees.

Step-by-step explanation:

Since the line is 180 degrees, and both of the angles that are measured would equal 180, then all we need to do is take 180 - 131 to get 49 degrees.  Hope this helped!
