Question

10sided polygons has 9 equal interior angles and 10 angle is 45 find the largest angle of polygon

Answer 1

Step-by-step explanation:

total angle measure of 10 sided polygon =

(n-2)×180

=(10-2)×180

=8×180

=1440

now 10th angle is 45degree

1440-45 = 1395

now, 1395/9= 155degree

this is why the other 9 angles are of 155degree each...

the biggest angle is 155
