Step-by-step explanation:

sum of all angles in a triangle is 180 degrees

x + 3x + 13 + x - 8 = 180

5x + 5 = 180

5x = 175

x = 37°

A = 3x + 13

3(37) + 13

A = 124°

** DISCLAMIER** am not completely sure. Please do not use my answer unless you are very desperate.

since O,R correspond with A,N I think you half F on each side and add it to 11.2 so
10 divided by 2 = 5
7 is already half.
5 + 7 is 12
12 + 11.2 = 23.2

IF THIS IS WRONG TRY 17
reason for 17:
10 + 7 = 17
If you look at both lines they look the same length as A, N.
