EXPLANATION
Let us choose zero to be our reference point. That is zero is representing the surface of the pool.
Since
Or
will be closer to zero.
We were told that
is where the boy's feet are. Therefore his feet are closer to the surface of the pool than the girl's feet.
So the correct answer is
the second option
Value of x is 10 duhhhhhh
Answer:
15 ft
Step-by-step explanation:
This problem can be represented by a right angle triangle, shown in the diagram below.
The distance between Jin and Zoe is the hypotenuse of the triangle, x.
According to Pythagoras theorem,
hyp² = opp² + adj²
Where opp is the opposite side and adjacent is the adjacent side to any angle of consideration (which is not important in this case)
Hence:
x² = 12² + 9²
x² = 144 + 81
x² = 225
Finding the square root:
x = 15 ft
Jin and Zoe are 15 ft apart.
