Answer:
It's C.
Step-by-step explanation:
You need to find the angles and find the sides by using a^2+b^2=c^2
You will need to use formula x= -b/2a because the min value will by the vertex of function.
x= -(-92/(2*.2)) = 230
then plug in x value
C=0.2(230)^2-92(230)+11,165= 585
14= -1/2 +4
subtract 4 from both sides
10= -1/2
times -2 on both sides
-20=1x
x= -20
