An expert diver is looking for a particular species of fish along the coast line he dives 22 feet below the surface of the ocean. Then he dives down seven more feet. He swims back up 14 feet and down another 4 feet before he finds the species of fish he is looking for. What was the depth at which the diver found the fish.

19 feets

Step-by-step explanation:

Given the following:

Initial dive depth = 22 feet

Additional dive = 7 feets

Swims back up for 14 feets and dives down another 4 feets before finally finding the fish.

Hence, depth at which the fish was found :

22 feets + 7 feets - 14 feets + 4 feets

29 feets - 14 feets + 4 feets

15 feets + 4 feets

= 19 feets

Hence, the depth at which the fish was found is 19 feets.

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
