Find the value of 2 in the triangle shown below.

Determine the equivalent system for the given system of equations: 5x − 3y = 6 x + y = 2

The image of abc is a'b'c. what transformations would result in this image? abc is reflected over the line x = 1, then is rotated -90° around the origin. abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1). abc is rotated 90° around the origin, then is reflected over the y-axis. abc is rotated -90° around the origin, then is reflected over the line y = -1.

What is the missing justification in the proof of the pythagorean identity below, sin^2x+cos^2x=1, using a right triangle?
