Question

the sum of five interior angle of decagon 432 if the remaining angle are in ratio 2 :3:4:6:9 . find the measure of the remaining angle ​

Answer 1

Answer:

84, 126, 168, 252 and 378

Step-by-step explanation:

Sum of the interior angles of a polygon = (2n-4)*90

Sum = (20-4)*90= 1440

Sum of remaining 5 angles = 1440-432 = 1008

Ratio of Remaining angles = 2:3:4:6:9

Sum of ratios = 2+3+4+6+9 = 24

Therefore the remaining angles are

2*1008/24, 3*1008/24, 4*1008/24, 6*1008/24, 9*1008/24

= 84, 126, 168, 252 and 378
