Six times the sum of a number and twelve is forty. Which equation represents this?
6N+12N=40
6N+12=40
6(N+12)=40

10.4 inches

step-by-step explanation:

2x2x2.6

x = 3 ± √(5+y)

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
