can someone explain to me how to do this?

We should know that the sum of the interior angles or an irregular polygon must be equal to 360°. For examples, the case of a square: 90° +90°+90°+90°=360°. So in our case, the sum of the angles is Sum=360°= (x+17)°+(2x+9)°+ (6x-5)° + meas OPQ, it implies measOPQ=360°-(x+17)° - (2x+9)° - (6x-5)° =360°-9x -31°=(329-9x)°

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
