[8] The hypotenuses must be congruent, DE and IJ
HL is hypotenuse-leg, or where the hypotenuse and one leg are congruent.
Since we see a leg is congruent, to prove they are congruent with HL we will need to know that the hypotenuses are congruent.
[9] Another leg, AC and YX
LL is leg-leg. Since we have one leg, we will need the other leg to prove the triangles are congruent by LL.
[10] A leg, DE and E? or FE and E?
LA means leg-angle. The angles by point E are vertical angles, so they will be congruent. To finish prooving the congruence using LA we will also need a leg.

The numerical representation and final elevation of the fish relative to sea level are :
- Final position = -13.52 + 7.8
- Final position = - 5.72
<u>Given the Parameters</u> :
Initial depth of fish = - 13.52
Change in elevation of fish = 7.8 feets
Positions below sea level are represented as negative values (-) ;
Hence, initial position of fish = - 13.52
Change in position = Rise in depth of 7.8 feets
<u>The numerical representation of the final position of the </u><u>fish</u><u> </u><u>can</u><u> </u><u>be</u><u> written thus</u> :
- Final position = Initial position + change in position
- Final position = - 13.52 + 7.8
Hence, the final position of the fish will be :
- Final position of fish = -13.52 + 7.8 = - 5.72

Answer:
(x-4)^2 + (y+5)^2 = 324
Step-by-step explanation:
The equation of a circle is given by the equation (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center point of the circle.
Therefore, since the center point of the circle and the radius is given, we can just plug the numbers into the formula:
(x-4)^2 + (y+5)^2 = 18^2
<u>(x-4)^2 + (y+5)^2 = 324</u>
First calculate the hourly rate, which is the difference of cleaning 2 and 1 rooms:
175-125=50
then calculate the initial value by subtracting the hourly rate from the "1 room" cost:
125-50=75
The initial cost might be something like driving to the place (which is only necessary once), while the rate covers work time or cleaning utensils used.
