1.	I need the answer of b and d
Answer» $\Large\bf{Answer:-}$ ❍ 720 ° Given :- The sum of interior angle of a triangle is 720° To find :- The side of the polygon. We know, The formula for the sum of interior angles in a polygon is $\small\bf \fbox \pink{180°(n-2)}$ Where n is the number of SIDES. Here, we can see that the sum of the interior angles is 720° Hence, $\sf{720 = 108(n - 2)}$ SINCE we NEED to find the n (number of sides) $\implies \sf \frac{720}{180} = n - 2$ $\implies \sf \: 4 \: = n - 2$ $\implies \sf \: n \: = 6$ Hence, the polygon has 6 sides. ❍ 540 $\small\bf\green{Let's\: do \:it \:mate}$ we know, $\implies\sf \: 180(n - 2) = 540$ $\implies\sf(n - 2) = \frac{540}{180}$ $\implies\sf(n - 2) = 3$ $\implies\sf \: n = 3 + 2$ $\implies\sf \: n = 5$ Hence the polygon has 5 sides. Answers :- B. The polygon has 6 sides. d. The polygon has 5 sides. $\small\bf\blue{Hope\:it\:helps\:uh\::)}$
