Each interior angle in a regular hexagon has measure of 120 degrees polygons with the same number of sides always have the same interior angle sum what is the sum of the interior measures on the irregular concave hexagon shown explain

step-by-step explanation:

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

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

answer: 100
