30 POINT REWARD!!! (haha I need to write 20 characters so that why this is here ps. please help)

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.

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.
