A submarine is only allowed to change its depth be Racing toward the surface in 60 meter stages. If the submarine starts off at 340 meters below sea level, what is its depth after 4 stages of rising to surface

Step-by-step explanation:

Given

Initial Level = 340 m

Number of stages = 4

Difference in each stage = 60 m

Required

Determine the depth of the submarine after 4 stages

First, we have to calculate the total distance moved towards the surface of the sea;

This is calculated as

This implies that the submarine moved a total distance of 240 metres;

It;'s new depth is calculated as follows;

Hence, its new depth after 4 stages of rising is 100m

what the question so we can you out

maybe - definition of supplementary angles. im not sure. sorry
