Question

the number of sides of the polygon in which the sum of the interior angle is equal to 14 right angles​

Answer 1

Answer:

9

Step-by-step explanation:

sum of the interior angles of regular polygon =14×90 = 1260°

(n - 2)×180 = 1260

180n = 1260 + 360

180n = 1620 => n = 9

no. of sides In that regular polygon= 9

Answer 2

Answer:

9

Step-by-step explanation:

sum of interior angles=14×90°=1260°

(n-2)×180°=1260°

n-2=1260°÷180°

n-2=7

n=7+2

n=9

so,the number of sides of the polygon=9
