If the hypotenuse of a right triangle is 10 inches long and one of its legs is 5 inches long, how long is the other leg?

inches long is the other leg

Step-by-step explanation:

Given the statement: If the hypotenuse of a right triangle is 10 inches long and one of its legs is 5 inches long.

Hypotenuse side = 10 inches

Let length of other leg be x.

Pythagoras theorem states that in a right angle triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Then; by definition of Pythagoras theorem;

Subtract 25 on both sides we get;

Simplify:

Simplify:

inches

Therefore, the sides of other leg is inches
