Question

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

Answer 1

Answer:

It is 12

Step-by-step 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 $m=12in$
