There is a formula for Sum of interior angles of a polygon:
$Sum = 180(n-2)$
This figure has 7 sides, n = 7
$Sum = 180(7-2) = 900$
Add up all the given angles,
Subtract from 900,
This will give you value of x.

The table represents a function. What is the value of f(–1)?

Afina-wow [57]

Answer : C

we need to the value of f(–1)

Table is given in the question

From the table ,

f(x) = 4 when x= -5, that is f(-5) = 4

f(x) = 0 when x= -1, that is f(-1) =0

f(x)= -1 when x=6, that is f(6) = -1

f(x)= -3 when x=9, that is f(9) = -3

So, the value of f(–1) = 0

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

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

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