Answer:
one triangle
Step-by-step explanation:
The given angle is opposite the longest given side, so this case is <em>not ambiguous</em>. These numbers define one triangle.
_____
<em>Comment on ambiguity</em>
The <em>law of sines</em> only gives rise to ambiguity (two solutions) only if the given angle is opposite the shorter of the two given sides, <u>and</u> the ratio of side lengths (short/long) is greater than the sine of the given angle.
In the extremely rare case of the side ratio being exactly equal to the sine of the angle opposite the shorter side, the triangle is a right triangle and there is exactly one solution.

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;
<em>Hence, its new depth after 4 stages of rising is 100m</em>
