The length of the other leg of the right-angle triangle will be √120 units. Then the correct option is B.
What is a Pythagoras theorem?
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
If a right-angle triangle has a hypotenuse of the length of 13 units and a leg of length of 7 units.
Let x be the third side of the right triangle.
Then the length of the other leg of the right-angle triangle will be
13² = x² + 7²
169 = x² + 49
x² = 169 - 49
x² = 120
x = √120 units
Then the correct option is B.
