Respuesta :

if xw is equal to wz then you can set up an equation using (g) as the lengths xw and wz

1g +1g+ 15 = 50 
this is the perimeter equation 
this simplifies to 
2g +15=50
 then you simplifiy using algebra 
2g=50-15
2g=35
g=17.5

Can you please award me BRAINLIEST if my answer is satisfactory!
Thanks!
