Answer:
Jim is 12.87 meters away from the shark.
Step-by-step explanation:
We are given that,
Distance between Jim and Tara = 20 meters.
The angle of depression of the shark from Jim and Tara is 47° and 40° respectively as shown in the figure below.
So, the third angle of the triangle formed is given by,
47° + 40° + ∠S = 180°
i.e. ∠S = 180° - 87°
i.e. ∠S =93°
So, now using the sine ratio formula, we have,
i.e. 
i.e. 
i.e. x = 12.87 meters
Thus, Jim is 12.87 meters away from the shark.
The result of the product of the sides of the triangles is 9
<h3>Shapes and Patterns</h3>
From the given diagram, you can see that the triangle and the shape circumscribed around it forms patterns given as:
- Product = sides of the triangle * number of sides of the circumscribed shape
For the circle and triangle
Product = 0 * 3
Product = 0
For the rectangle and triangle;
Product = 3 * 4
Product = 12
For the two triangles
Product = 3 * 3
Product = 9
Hence the result of the product of the sides of the triangles is 9

Answer:
B
Step-by-step explanation:
So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.
Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.
Heres what we know however:
angle 1 + angle 2 = 180 degrees.
How do we know this?
Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.
Lets input that into our nice lil equation to get an answer:
7 degrees+angle 2 = 180 degrees
Now lets solve.
Subtract 7 on both sides, and your left with:
angle 2 = 173 degrees.
So the answer must be:
<u>173 degrees</u>
Hope this helps! ;)
