Katherine wants to prove that the measures of the interior angles of a triangle have a sum of 180. She draws a triangle and extends one of the sides through a vertex. She then draws a line through this vertex that is parallel to the opposite side

As we know, if we add up the interior and exterior angles of one corner of a triangle, we always get 180. the exterior angle in question is equal to the sum of the other two angles in the triangle

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
