Please help with these

A) √29 = x   B)  x = √41.8   C) √109 = x    D) x = √489.24

Step-by-step explanation:

A) 2² + 5² = x²

    4 + 25 = x²

          29 = x²

        √29 = x

B) 3.6² + x² = 7.4²

 12.96 + x² = 54.76

-12.96          - 12.96

              x² = 41.8

              x = √41.8

C) 3² + 10² = x²

    9 + 100 = x²

           109 = x²

          √109 = x

D) 7² + x² = 23.2²

    49 + x² = 538.24

    -49           -49  

            x² = 489.24

            x = √489.24
