What is the measure of arc KP if the measure of the inscribed angle is 50 and the measure of its arc is 25

Someone me! will award brainliest if u explain and answer!

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.

Write an equation of the parabola with the focus point of (0,1/3) and vertex at the origin. use x for the independent variable. explain. need !
