ANSWER

(n - 2) \times 180 \degree

EXPLANATION

The sum of the interior angles of a triangle is 180°

We can rewrite this as:

1 \times 180 \degree = (3 - 2) \times 180 \degree = 180 \degree

The sum of interior angles of a quadrilateral is 360°

We can also rewrite this as:

2 \times 180 \degree = (4- 2) \times 180 \degree = 360 \degreeIn general an n-sided polygon has

the sum of the interior angles given by the formula:

(n - 2) \times 180

A length of string that is 240 cm long is cut into three pieces the second piece is 25% longer than the first piece the third pi
Tresset [83]
Hey there,
Let's say that the first piece is x cm
1st = x
2nd = x + 25%
3rd = x - 25%
100% = 240 cm
1% = 240 / 100
      = 2.4cm
x + x + 25 + x - 25 = 100
3x + 25 - 25 = 100
3x = 100 - 25 + 25
3x = 100
3x = 240 cm
x = 240 / 3
   = 80 cm
1st piece = 80 cm
2nd piece = 80 + (25% x 80)
                = 80 + 20
                = 100cm
3rd piece = 80 cm - (25% x 80)
                = 80 cm - 20
                = 60cm

Hope this helps :))
