Yes - they have to be similar.  Since they are using the same line as the hypotenuse, the ratio of the other two sides are in the same ratio (ie, the slope of the line), the 3 inner angles will be the same.  Thus, the triangles will be similar.

Answer:e
Step-by-step explanation:
The equation for the submarine is given as y =-240x
Where y is the distance of the descent
x is the time in hours
and -240 is the rate of distance per unit time
To calculate how long it will take this submarine to reach the descent
x = y /-240
