Final answer:
The length of the hypotenuse of the triangle can be found using the Pythagorean theorem. In this case, the length is approximately 20.07 units.
Step-by-step explanation:
The length of the hypotenuse of the triangle can be found using the Pythagorean theorem. The theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, the adjacent side is 1.7 and the opposite side is 20. Therefore, the hypotenuse can be calculated as follows:
c = √(a)² + (b)²
c = √(1.7)² + (20)²
c = √(2.89 + 400)
c = √(402.89)
c ≈ 20.07
Therefore, the length of the hypotenuse is approximately 20.07 units.
