find the number of sides a polygon has if the sum of the measures of the interior angles is (i)50 right angles (ii)1800°.
Answers
Answer:
Step-by-step explanation:
(i) 50 right angles= 50x90= 450
Fx for the interior angle sum property= (n-2)180
:. (n-2)180=450
=>n-2=450/180
=> n-2= 2.5
=> n= 4.5 sides( Bruh, what kinda question is this??)
(ii)(n-2)180= 1800
=> n-2= 1800/180
=> n-2= 10
=>n= 12 sides

Step-by-step explanation:
i) 50 right angles
50 right angles =50 ×90
= 4500
The sum of the interior angles of the polygon = (n-2)×180
(n-2)×180=4500
180n-360=4500
180n = 4500 + 360
180n = 4860
n = 4860 / 180
therefore n = 27 answer
ii) 1800
The sum of the interior angles of the polygon = (n-2)×180
=> (n-2) × 180= 1800
=> 180n - 360 = 1800
=> 180n = 1800+ 360
=> 180n = 2160
=> n = 2160/180
therefore n = 12 answer
