Analyze the triangles shown. Steve determines that sides DK and BC are congruent. He also measures Z K and Z C and determines that they are congruent. He concludes that the triangles are congruent by the SAS Congruence Theorem. Is Steve correct? If he is incorrect, which congruence theorem should Steve use? Explain your reasoning and show all of your work including measurement of angles and/or line segments.

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
