Question

The sum of seven angles of a nonagon is 1000. The other two angles are equal to each other. Calculate the size of the other two angles.

Explain the solution

Answer 1

Answer and Step-by-step explanation:

In a nonagon, n=9. sum of angles= (9-2)*180° =7*180° =1260° sum of seven of the angles=1000° sum of the other two angles=1260°-1000° =260° size of each angle=260°/2=130°.
