this is kind of a pain but since the sum of the interior angles = (n-2)*180 where n is the number of sides, you can write expressions for each of the interior angles and sum them up to (n-2)*180
for example, since the straight line AE is made of angle A and angle (6x-3), you can re-write angle A as 180 - (6x-3) repeat this process for angles B, C, D, E
so what would be the answer
I'm not going to do all the work for you let's take it one step at at time: notice how BC is a straight line, making two angles, angle B and the angle (4x+8) since all angles on a straight line sum up to 180, angle B = 180 - (4x+8) repeat this logic with angles C, D, E.
14(10) + 6 = 146°
right?
where are you getting x = 10 from
so just take out the 10?
we are not solving for x right now, we are setting up the equations for interior angles A, B, C, D, and E
