Question

In wxy,wy is congruent to xy the perimeter of wxy is 76 inches,how many inches is wx

Answer 1

It is 12

Explanation:

Answer 2

If wy is congruent to xy, then from w to y is equal to the distance between x and y. According to the figure, both distances are 3m-4 each. Therefore the perimeter is the sum of the three sides, namely:


`p = m + (3m-4) + (3m-4)=76in`

Solving for m:

`m + (3m-4) + (3m-4)=76`

`7m-8=76`

`7m=84`

`m=12`

Finally:
wx is the distance
`m=12in`
