Answer:

-0.4 or \frac{-2}{  5}

Step-by-step explanation:

tan^-^{1} ({\frac{2}{5} })=21.80\\

tan ( 2π-21.80)

but 2π = 360

Therefore our question becomes:

tan ( 360-21.80)=tan(338.2)= -0.4

Answer:

Sum of interior angles of 12 sided object = 1800°

Step-by-step explanation:

Formula to calculate the sum of interior angles of a polygon is,

Sum of the interior angles of a polygon = (n - 2) × 180°

Where n = number of sides of the polygon.

If number of sides of a polygon are 12,

For n = 12,

Sum of interior angles = (12 - 2) × 180°

                                     = 10 × 180°

                                     = 1800°

Therefore, sum of interior angles of a 12 sided polygon will be 1800°.

19,432÷x=48 Remainder 232 (Plz help its for my hw that's due tmrw)
Neko [114]

Answer:

x = 404.83

Step-by-step explanation:

The given expression is :

19,432÷x=48 ...(1)

We need to find the value of x.

\dfrac{19,432}{x}=48

Cross multiplying both sides,

19,432=48x

Dividing both sides by 48

\dfrac{19,432}{48}=x\\\\x=404.83

So, the value of x is 404.83.
