Answer:

180 degrees.

Step-by-step explanation:

If diameter AB forms half of a circle, then that is 180 degrees. Arc ABC is the other half of the circle. Therefore, 180 plus x equals 360. Subtract 180 from both sides and you get 180 degrees. Hope this helps!

Answer:

Length ≈ 31cm

Width ≈ 10cm

Step-by-step explanation:

$Let -the-length-be : x\\Let-the-width-be :y\\\\According- to- the- question ; \\x = 3(y)\\x=3y ---------(1)\\2(l+w)=82\\2(x+y)=82\\2x+2y =82 --------(2)\\Substitute- the - given- value- for ; x -in - equation---(1) into -equation (2)\\2(3y)+2y =82\\6y+2y=82\\8y =82\\\frac{8y}{8} =\frac{82}{8} \\y = 10.25\\\\Substitute 10.25 -for ;y -in -eq 1\\x=3y ---------(1)\\x = 3(10.25)\\x = 30.75$
