Answer:
Angle X is 122°
Step-by-step explanation:
Because it's a 180° line (supplementary angle thm):
180°-58°=122°
Since five 20's equal one hundred, multiply 4200 by 5 and get 21,000

Formula for Perimeter of Rectangle:
P = 2(L + W)
Plug in 160:
160 = 2(L + W)
L = 4W
So we can plug in '4W' for 'L' in the first equation.
<span>160 = 2(L + W)
160 = 2(4W + W)
Combine like terms:
160 = 2(5W)
160 = 10W
Divide 10 to both sides:
W = 16
Now we can plug this back into any of the two equations to find the length.
L = 4W
L = 4(16)
L = 64
So the width is 16, and the length is 64.</span>
