Given:
The figure of a right angle triangle.
Hypotenuse = 
in.
To find:
The missing lengths of the sides.
Solution:
In the given right angle triangle both legs a and b are equal, and hypotenuse is in.
Using Pythagoras theorem, we get
![[\because a=b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%3Db%5D)
Divide both sides by 2.
Taking square root on both sides.
Side cannot be negative. So,
Thus, the missing side lengths are a=9 in and b=9 in.
Therefore, the correct option is C.
Following are the dependent variables:
<em>1. The amount of water that each orchard receives.</em>
<em>2. The species of trees in the orchard.</em>
Reason:
The exercise scientist is looking for the effects of a chemical between an apple crop to which it is administered and another to which it is not, 4 options are presented, of which it is essential to count as a variable the amount of water each Orchard and tree species in the orchard, since they can generate alterations in the results, the other two variables of the exercise such as number of apples and size of the orchards are not significant and their variations do not affect the scientist's objective.

Answer:
Choice A
Step-by-step explanation:
- SSS is not applicable as only 2 sides are congruent
- HL is lot applicable as triangles are not right angled (∠A and ∠E >90)
- ASA also not applicable as the angle should be included but is not
