Diagram C shows the inverse of P(x).
a) Same-side interior angles
b)

c) They are parallel by the same-side interior angles theorem.
Draw a circle, then take and draw lines across it for however many you want. circles have infinite lines of symmetry so anything works.
The answer is 90 miles per hour.
Leg * /2 = hypotenuse
Hypotenuse divided by /2 = leg
12 divided by /2
Rationalize denominator:
12 * /2 divided by by /2 * /2
Simplify denominator:
12 * /2 divided by 2
Simplify:
6 * /2 or 4.24
Both x and y because it’s a 45-45-90 triangle
