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).
Answer:
C. 110
Step-by-step explanation:
The correct answer will be: $31 = $4a + $3s (y = mx + b) meaning if Mr. Steele buys 4 adults tickets then he also bought 5 student tickets. $31 = 4(4) + 3(5) -- 31 = 16 + 15 -- 31 = 31
