Question

find the number of sides of a polygon if the sum of its interior angle is 10 right angles​

Answer 1

Answer:

7 sides

Step-by-step explanation:

10 right angles=10*90=900

let the number of sides be n

sum of interior angles=(n-2)*180

=900=(n-2)*180

=900/180=n-2

=5=n-2

=5+2=n

=7=n

Thus, the number of sides are 7.
