A. 7
Step-by-step explanation:
my unit test review said the other persons answer was wrong and it said this was right so ya.
The length of one leg of the given triangle is 1 unit.
The square of the hypotenuse is equal to the sum of the squares of other two sides.
Given the following parameters;
Hypotenuse = √2
If the lengths of the other two sides are congruent, thus;
x² + x² = (√2)²
2x² = 2
x² = 2/2
x² = 1
x = 1
Hence, the length of one leg of the triangle is 1 unit.
