A geometric figure created without using tools is a sketch.
3/8=x/20
Multiply both sides by 20.
20(3/8) = 60/8 = 15/2 = 7.5
7.5 = x
You FOIL (First, Outer, Inner, Last)
If you FOIL, you should get 2y^2 - 4y + 4y^2 - 8y +12y -24
The sum of the interior angles of this shape is 360 degrees. You would do 133 + 86+41 and then subtract the sum from 360. You get 100° as the answer
