Romashka [77]

9514 1404 393

Answer:

  BD = 14

Step-by-step explanation:

The Pythagorean theorem can be used to find the lengths of CD and BC.

  CD² +12² = 13²

  CD = √(169 -144) = √25 = 5

__

  BC² +12² = 15²

  BC = √(225 -144) = √81 = 9

__

The length BD is then ...

  BD = BC +CD

  BD = 9 + 5 = 14

The length of side BD is 14 units.

The length of a rectangular piece of steel in a bridge is 2 meters less than triple the width. The perimeter of the piece of ste
Sholpan [36]
This is an algebraic equation. First we have a square the width is X
The length is L=3X-2. P (perimeter is 44)
Therefore P = 2L+2X
                    = 2(3x-2) + 2x
                    = 6x - 4 + 2x
                    = 8x - 4
            44+4=8x
                  x=48/8
                  x=6

Ans: Width is 6 metres and length is 16 metres
