Look at the diagram.
45
Three students are asked to write and explain an equation to determine the value of x. The answers for each student are shown in the tab
Sebastian
x + 110 + 45 = 180, because the sum of the interior angles of a triangle equals 180
Lilly
x + 110 = 2.8x, because the sum of the measures of remote interior angles is equal to the measure of the exterior angle.
LaShonda
155 +2.8x + 135 = 360, because the sum of the exterior angles of a triangle equals 360°
Which student(s) wrote a correct equation and explanation?
A
Sebastian only
B
