Question

the sum of all interior angles of polygon is equal to 14 right angles.find the number of sides of the polygon

Answer 1

Answer:

Number of sides a polygon have are 5

Step-by-step explanation:

If the sum of its interior angles is 14 right angle  

Sum of interior angles of a polygon = 180(n−2)

=> 180(n−2)=14×90

=> 180(n−2)=14×90=> (n−2)=1260/180

=> (n–2)=7

=> (n–2)=7=> n=7+2

=> (n–2)=7=> n=7+2=> n=9

=> (n–2)=7=> n=7+2=> n=9Number of sides in polygon is 9

So this is your answer

Hope this help you
