Find the measure of each angle in triangle abc. a= 48-x b=9x-38 c=90 a) a = 58 b=128 c= 90 b) a=128 b=58 c=90 c) a=38 b=52 c=90 d) a=52 b=38 c=90 no guessing and show work you.

The 3 angles of a triangle must add to 180. always. since one of our angles (c) is given as 90 already, the other 2 must add too 180-90, or 90. the 2 angles are 48-x and 9x-38, which Sim to 8x+10. if 8x+10=90, then x=10 (I assume you are ok with the algebra). then a=38 and b=52
