First one..................
To find it it is
ax^2+bx+c
if the first term (a) is 1 then c=b/2
b=-1/4
(-1/4)/2=-1/4 times 1/2=-1/8
k=-1/8
Answer:
The answer is 76.
Step-by-step explanation:
≅ means to be equal to.
☆Angle DGE ≅ EGF.
Therefore, 3x + 8 = 5x - 12
☆Let's solve that equation.

We found the value of x which is 10.
☆Let's Now plug in.

and the other:

☆They asked for what the angle of DGF measured. So we would have to add both sides

☆The answer is 76
You do add the two negatives and get a negative answer but -3 + -5 = -8
