Answer:
10 units.
2√7 units.
- (or 5.29 units to the nearest hundredth)
Explanation:
If the 2 sides are legs of the triangle ( that is they are at 90 degrees to each other) the third side, by Pythagoras theorem:
= √(6^2 + 8^2)
= √100
= 10 units.
The other possibility is that 8 is the length of the hypotenuse, in which case
The third side
= √(8^2 - 6^2)
= √28
= 2√7 units.
