I hope this helps you
2x+x-10=4
3x=14
x=14/3
y=14/3-10
y=14-30/3
y=-16/3
When only angles are specified, the sides can be any length, so the triangle is not unique. In any event, the sum of angles must be 180°, so three angles measuring 50° cannot be closed to form a triangle.
Three sides measuring 4, 8, and 14 ft cannot be closed, either, as the long dimension exceeds the sum of the other two. The ends can't meet.
The appropriate choice is the 3rd one ...
... three sides measuring 5 in, 12 in, and 14 in.
7 14/18 since you can reduce this to 7 7/9:)
Just something that is true or are there choices? If just something true then dialated by 1 is always the same as the original shape.
