The shorter leg of a right triangle is 6 m shorter than the longer leg. The hypotenuse is 6 m longer than the longer leg. What are the side lengths of the triangle?
1 Answer
Length of the longer side =
Length of the shorter side =
Length of the hypotenuse =
Explanation:
From the data given, we can write:
Length of the longer side =
Length of the shorter side =
Length of the hypotenuse =
The Pythagorean Theorem states the the square of the hypotenuse is equal to the sum of the squares of the other two sides. Hence.
Cancel equivalent terms on each side.
Subtract
Factorise.
Since the length has to be a positive integer, the length of the longer side is
Hence:
Length of the longer side =
Length of the shorter side =
Length of the hypotenuse =
To verify, we apply the Pythagorean Theorem:
Since the two sides are equal, the calculations have been verified.
