Complete question :

A scuba diver is swimming in the ocean 10 feet below sea level. Then, she dives down 12

more feet to get a better look at a coral reef.

What is the scuba diver's final position relative to sea level?

- 22 feets

Step-by-step explanation:

Given that:

Starting position of scuba diver = 10 feets below sea level = - 10 feets

Then a further descent of 12 feets in other to get a better look of the coral Reef

Further descent = - 12 feets (below sealevel)

Hence, Final position of the scuba diver will be:

Starting position + depth of further descent

(-10 + - 12) feets

-22 feets

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
