Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in
Answer:
x = 16° z = 67°
Step-by-step explanation:
9x - 77 + 7x + 1 = 180
16x = 256
x = 16°
z = 16 x 9 - 77
z = 67°
