Draw each of the following, if you can. If you cannot, explain the reason. (a) A 10-vertex forest with exactly 12 edges (b) A 12-vertex forest with exactly 10 edges (c) A 14-vertex forest with exactly 14 edges (d) A 14-vertex forest with exactly 13 edges (e) A 14-vertex forest with exactly 12 edges

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

3x^3-2x^2+4x-3= -3

x^2+3x+3= 3

-3÷3= -1
