Awater heater tank holds 280 gallons. twenty percent of the water is lost as steam how many gallons remain to be used?

Hello,

We calculate the quantity of lost water :

280 × 0,20 = 56

The number of gallons which it remains to use is :

280 - 56 = 224 gallons

Bye ;)

step-by-step e

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
