A = 1 + 5^3-x, Isolate the variable by dividing each side by factors that don't contain the variable.
Your answers would be c and d because angles across from the exterior angle are equal to it
One leg is horizontal, on the line y=3. Another leg is vertical, on the line x=1. The point where these intersect, D(1, 3) is the vertex of a right angle. Any right triangle inscribed in a circle has its hypotenuse as the diameter of the circle.
Since the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse: ((8, 3) + (1, -5))/2 = (4.5, -1).
The answer is P= 80/19
hope this helps
