The angle measures of a triangle are shown in the diagram.
What is the value of x?

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?

What are the solutions of the equation x4 + 6x2 + 5 = 0? use u substitution to solve.

Pls i’m super dumb and i need with this one it’s due tomorrow
