Answer:
Mario ate 27.27% of her cookies
width = 83 cm
Perimeter = 2(width) + 2(length)
So if l = 99 cm, and p = 364, then
364 = 2w + 2(99)
364 = 2w + 198
166 = 2w
w = 83 cm
<u>The angle based on the diameter is always right</u>
Then <ABC=90 and ∠BAC=∠ACB=45° ; and ∠BCD=180-45=135 then x=(180-135):2=22,5°
