Since it says that T is the midpoint that means it equal divided the line. So,
X+3 must equal 4x
X+3 =4x
Subtract x on both sides
3=3x
Divide 3 on both sides
1=x
Plug in x into equation
4(1) =4
TU =4
9×1=09
9×2=18
9×3=27
as you can see the algorithm would most likely be deducting one from the second digit and adding it to the first digit
Zero.
The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.
