Step-by-step explanation:

A diagonal divides a polygon into two parts. Drawing all of the diagonals from a given vertex to the other non-adjacent vertices will divide the polygon into triangles.

The angle sum theorem tells you the sum of triangle angles at any polygon vertex will be equal to the measure of the interior angle of the polygon at that vertex. Since we're concerned only with triangles created by drawing diagonals between non-adjacent polygon vertices, the sum of triangle angles will be the sum of polygon angles.

So, you can multiply the number of triangles by 180° to find the sum of interior angles of the polygon. (The number of triangles is two fewer than the number of polygon sides.)

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
