In a right- angled triangle, one side is 8.3cm and another is 7.7. How do you find the perimeter of the triangle?
I see two cases in the following problem.
CASE 1: FINDING THE HYPOTENUSE
Let's say that you need to find the hypotenuse
Using Pythagoras' theorem, we got:
Therefore, the perimeter will be
CASE 2: FINDING THE OTHER LEG
If the hypotenuse is already given, in this case,
Substitute in given values,
And so, the perimeter here will be
