The atlantic ocean covers about 3.2 × square miles. the pacific ocean covers about 6.4 × square miles.
about how much area does the atlantic ocean and pacific ocean cover?

The Atlantic Ocean and Pacific Ocean covers about

Step-by-step explanation:

Let

x -----> area covered by the Atlantic Ocean

y -----> area covered by the Pacific Ocean

we know that

The area that covers the Atlantic Ocean and Pacific Ocean is equal to the sum of  the area covered by the Atlantic Ocean and the area covered by the Pacific Ocean

so

we have

substitute

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
