Answer:
C. 10
Step-by-step explanation:
Two sides of the right triangle are equal to each other, which is 5√2.
The third side is the hypotenuse length = x
We can use pythagorean theorem to find x.
Thus,
c² = a² + b²
Where,
a = 5√2
b = 5√2
c = x
Therefore:
x² = (5√2)² + (5√2)²
x² = 50 + 50
x² = 100
x = √100
x = 10
