a triangle is such that the first side is twice the length of the second side .the third side is 4meters long. if the perimeter of the triangle is 13m find the length of the first and second sides.​

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?
