Question

I need the answer of b and d​

Answer 1

$\Large\bf{Answer:-}$

❍ 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.
