Final answer:
To find the length of the hypotenuse of the triangle, use the Pythagorean theorem.
Step-by-step explanation:
The base length of the triangle is (3x-4) and the altitude is 2x.
To find the length of the hypotenuse of the triangle, we can use the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So, the length of the hypotenuse is:
√((3x-4)^2 + (2x)^2)
