65.50/100 52.40/x
65.50/52.40= 1.25
100/1.25=80
52.40/80
The answer is 80
X = -b/2a, given that the function is in the form y = ax^2 + bx + c
Answer:

Step-by-step explanation:
ASA (Angle-Side-Angle) is a proof of congruence that states if two triangles share two angles and the side between those two angles, the triangles are congruent. In problems 1 and 2, the following demonstrate this:

In problem 3,
is known in geometry as the Reflexive Property. Because of this, the two triangles in the diagram for problem 3 now share two angles and the side between them, thus they are congruent from ASA (Angle-Side-Angle).
