Answer:

3y = 60°, 2y = 40° , 4x = 104°, x = 26°, y = 50°

Step-by-step explanation:

Triangle g

180° = 80° + 3y + 2y

100° = 5y

y = 20°

Triangle h

y = 180° - 130°

y = 50°

180° = 4x + x + 50°

130° = 5x

x = 130 / 5

x = 26°

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

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

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

What is the inequality?

crimeas [40]

Answer:

$y\leq \frac{1}{2}x+2$

Step-by-step explanation:

we know that

The solution of the inequality is the shaded area below the solid line (the inequality is of the form $y\leq mx+b$ )

The y-intercept of the solid line is (0,2)

The x-intercept of the solid line is (-4,0)

The slope of the solid line is

$m=(0-2)/(-4-0)=\frac{1}{2}$

The equation of the solid line is $y=\frac{1}{2}x+2$

therefore

The linear inequality represented by the graph is

$y\leq \frac{1}{2}x+2$

5(x+6)+11=25-3x what is the answer?

Zolol [24]

This is how I did it:
$5(x + 6) + 11 = 25 - 3x$ use distribution
$5x + 30 + 11 = 25 - 3x$ use addition
$5x + 41 = 25 - 3x$ use addition and subtraction
$8x = -16$ use division
$x = -16/8$
$x = -2$

So your answer is $x = -2$
