Someone help please! :)

let angle A be 'x' degrees. then angle B would be '3x+6' degrees and angle C would be 'x+39'. sum up these angles and equate them to 180. then solve for x
OpenStudy (ny,ny):

so 4x + 45 = 180
after calculations you get:
4x = 135
More calculations...
x = 33.75
OpenStudy (ny,ny):
x= a
OpenStudy (anonymous):
Huh?
SHouldn't it be a number?
OpenStudy (ny,ny):
33.75 = a
107.25 = b
72.75 = c
OpenStudy (ny,ny):
