Answer:

  60

Step-by-step explanation:

The exterior angles of the polygon are the supplement of the interior angles, so are ...

  180° -174° = 6° . . . . measure of each exterior angle

The sum of exterior angles is 360°, so ...

  n(6°) = 360°

  n = 360°/6° = 60

The polygon has 60 sides.

Answer:

The polygon has 60 sides.

Step-by-step explanation:

Each interior angle = 174°

Each exterior angle = 180° - 174° = 6°

Sum of all exterior angles = 360°

6x = 360° (<u>x</u> <u>=</u> <u>no</u>. <u>of</u> <u>exterior</u> <u>angles</u>)

x = 360°/6

x = 60

If it has 60 exterior angles it has 60 interior angles.

A standard city block in Manhattan is a rectangle measuring 80 m by 270 m. A resident wants to get from one corner of a block to
kondor19780726 [428]

Answer:

68.4 meters shorter

Step-by-step explanation:

ok so you want to compare the distance  80 m + 270 m with the diagonal length.

the diagonal length =  root ( 80^2   +  270^2 )

diagonal length = root(6400 +  72900)

diagonal = root(79300) =281.602 m

so.

350 - 281.602 = 68.397 meters  about  68.4 meters  shorter than walking around

Solve using the quadratic formula: 2x2-9x+12=0
marta [7]

Answer:

no solution

Step-by-step explanation:

For getting the nature of solution of the quadratic equation of the form:

ax² + bx + c = 0

We need to find Discriminant which is:

Discriminant (D) = b² - 4ac

  • If D < 0, there is no solution of equation.
  • If D = 0, there are two equal and real solution of equation
  • If D < 0, there are two real and distinct solution of equation

Here we have equation is:

2x² - 9x + 12 = 0

∴ a=2, b = -9, c = 12

⇒ D = 81 - 4 × 2 × 12 = -16 < 0

Hence, there is no solution of given equation.
