Answer:
We know from Pythagoras theorem that Square of hypotenuse = Sum of squares of other two sides Now by substituting the values from the question we get...
Let the missing side be x
61² = x² + 11²
changing signs as changing sides
=> x² = 61² - 11²
=> x² = 3721 - 121
=> x² = 3600
=> x = √3600
=> x = 60
So the length of other side is 60cm
