Answer: Memorise the rule that the sum of the interior angles of a polygon = (n-2) × 180°, and that each interior angle of a regular polygon can be calculated by the rule: (n-2) × 180° / n, where 'n' refers to the number of sides.

Step-by-step explanation:

remeber this rule

sum=(n-2)*180°

n is no of side

take that away from 2

multiply 180

e.g triangle

3 sides

take away 2

3-2 is 1.

multiply by 180

1*180 is 180°

Which statements apply to the expression

bagirrra123 [75]

Answer:

A, C, D, F

Step-by-step explanation:

Given the expression : (3/5)³

Recall :

a^b where, a = base ; b = exponent

In ; (3/5)^3

Base = 3/5 ; exponent = 3

Similarly ;

a^b = a in b places

(3/5)^3 = (3/5) * (3/5) * (3/5)

(3/5) * (3/5) * (3/5) = (3*3*3) / (5*5*5) = 27/125

Hence, A, C, D and F are all correct

What’s the distance formula

Whitepunk [10]

Step-by-step explanation:

$\text{Let}\ A(x_1,\ y_1)\ \text{and}\ B(x_2,\ y_2).\ \text{Then the distance between}\ A\ \text{and}\ B\ \text{is:}\\\\|AB|=\sqrt{(x_2-x_1)^2+(y_2-y1)^2}\\\\Example:\\\\A(2,\ 5),\ B(-1,\ 1)\\\\|AB|=\sqrt{(-1-2)^2+(1-5)^2}=\sqrt{(-3)^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$
