Answer:
C
Step-by-step explanation:
Since the triangle is right with hypotenuse h
Use Pythagoras' identity to solve for h
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
h² = ( 5[tex]\sqrt{2}[/tex] )² + ( 5[tex]\sqrt{2}[/tex] )²
= 50 + 5 0 = 100
Take the square root of both sides
h = [tex]\sqrt{100}[/tex] = 10 → C
