Question

A 6
2) 8
3) 9
1. Four angles of a nonagon are 50°, 60°, 70°, 40° respectively. And all the other angles are equal
Then the measure of each one of the equal angles is
1) 220°
3) 240
4) 260
ngles so obtained are
2) 208​

Answer 1

The measure of all the angles of nonagon = 1260 degrees
Four angles = 50, 60, 70, 40.

All the remaining angles are equal
Let the remaining angles be x
50 + 60 + 70 + 40 + 5x = 1260
220 + 5x = 1260
5x = 1260 - 220
5x = 1040
x = 1040/5
x = 208

Therefore, the answer is option 2 (208)
