13. 12 3/8
14. 9 2/3
15. 3 4/10
16. 3

so... what does that give you for the discriminant?
if it's a negative value, no solutions
if it's a positive value, two solutions
if it's 0, one solution
8x + 3c = 2200
11xc= 2200
2200÷11
200
200xc
I think the answer is 2 and -15. Because 2 times - 15 is -30 and 2 and -15 can be added to -1.
Part 1) Find the measures of angle BGEwe know that
The inscribed angle measures half of the arc it comprises.
so
angle BGE=(1/2)*[arc EB]
Part 2) Find the angle BDG
we know that
The measure of the external angle is the semi-difference of the arcs that it covers.
so
angle BDG=(1/2)*[arc GEB-arc GB]
