William arcenio is remodeling his home. In order to save money, he is upgrading the plumbing himself. He needs 36 pieces of copper tubing, each 2/9 of a foot long. If he has 11-foot piece of tubing, will that be enough? How much more does he need or how much tubing will he have left over?

He needs 2 feet more tubing.

Step-by-step explanation:

William Arcenio needs 18 pieces of copper​ tubing, each 2/9 of a foot long.

So, total length needed = 2/9 x 18 = 4 feet

He has a 2​-foot piece of​ tubing.

So, he does not have enough tubing.

He needs 2 feet more tubing.

none.

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
