Answer:

110.98 m

Step-by-step explanation:

you have a right triangle and you know the adjacent side to the 25 degree angle and are looking for the opposite side of the angle

tan of an angle = opposite side/adjacent side

Let d = depth of submarine

So, tan 25 = d/238

     238 tan 25 = d

d =  110.98 m

Note:  You must memorize the definitions of all the trig functions and then these types of problems will be easy.  OK?
