In a 2

In a thirteen sided polygon, the sum of five angles is 1274°, four of the eight angles remaining are equal and the other four are 18° less than each of the equal angles. Find the angles. .

Result

A =  97.25
B =  79.25

Solution:

1274 + 4A + 4B = 180*(13-2)
B = A - 18

4A+4B = 706
A-B = 18

A = 3894 = 97.25
B = 3174 = 79.25
