The triangles are similar. what is the value of x? show your work.

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.

The table above shows approximate conversions from gallons to liters. what is the value of x?
