1.What is the perimeter of the trapezoid shown?
2.Parallelogram ABCD has area 144, with AB=16 and BC=12. Find the length of segment DX.
For the first one, split the trapezoid into 2 triangles and a rectangle, then use the ratios of a 30 60 90 triangle to solve. :)))
For the second one, remember that AB = DC, and then you should be able to use pythagreon for it.
