A right angle is 90 degrees, so~
2x+4 +2x-1+4x+2 = 90
(these are the angles' equations)
Combine like terms
8x+5 =90
    -5     -5
8x = 85
/8    /8
x=10.625
BUT YOU AREN'T DONE YET ;D
Plug in x and solve the equations.
~Hope this helps~

(2x+4)+(4x+2)+(2x-1)=180
8x+5=180°
8x=180-5
8x=175
X=21.875
A= 2(21.875)+4=47.75
B=4(21.875)+2 =89.5
C=2(21.875)-1=42.75
