Answer:
(1/2,7/4)
Step-by-step explanation:
x=-b/2a
x=1/2
y=(1/2)^2-(1/2)+2
y=1/4-2/4+8/4
y=7/4
First of all, triangles angles add up to 180 degrees.
BCD=120. To find BCA subtract 180-120 to get 60 degrees.
We know what ABC is, it equals 85, so far we have 2 angles.
Lets add them up, 85+60=145
Since the angles must add up to equal 180 we're going to subtract 180-145
Which equals 35, BAC=35 degrees.
