The sum of interior angles of a polygon measures 11,520. How many sides does the polygon have?

1 answer:

4 0

The sum of angles in a regular n sided polygon:

(n - 2)*180

(n - 2)*180 = 11520

(n - 2) = 11520/180

(n - 2) = 64

n - 2 = 64

n = 64 + 2

n = 66

Polygon has 66 sides.

completa con las razones trigonométricas de cada triángulo rectángulo dado y encuentra el lado faltante aplicando el teorema de

Rus_ich [418]

primero vamos a calcular el lado faltante usando el teorema de pitagoras para poder obtener el lado faltante a

$a=\sqrt[]{hipotenusa^2-cateto^2}$ $a=\sqrt[]{100^2-85^2}=52.68$

a=52.68 m

teniendo el lado faltante podemos calcular las razones trigonometricas

$\sin (55)=\frac{85}{100}=0.85$ $\cos (55)=\frac{52.68}{100}=0.52$ $\tan (55)=\frac{85}{52.68}=1.61$

$\csc (55)=\frac{100}{85}=1.17$ $\sec (55)=\frac{100}{52.68}=1.89$ $\cot (55)=\frac{52.68}{85}=0.61$
