4.41 because .409 rounds up to .41,
Answer:
16
Step-by-step explanation:
adding any two sides of a triangle is allways greater than the third side
(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
I hope this helps you
4x>-4 x>-1
8x <32 x <4
-1 <x <4
