Can you draw an isosceles triangle with only one 80 degree angle?

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.

How do you solving the solution of each system using elimination?
