The phone lines went down during the snow storm and 1,234 miles of phone cable will to be checked. If the workers are to thoroughly check 6 miles of cable each day, how long will it take to check all of the phone cable? Record your solution on a piece of paper including an equation and labels.

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
