Answer:

40°

Step-by-step explanation:

Measure of Nonagon (9-sided polygon) = 1260°

Each angle measure = 1260 ÷ 9 = 140°

The value of x (the outside angle) = 180° - 140° = 40°

HELP HELP HELP Quick algebra 1 question What is the slope of this graph?

Nataly [62]

Hello and Good Morning/Afternoon:

To find the slope of something:

⇒ let's consider what the formula of the slope needs

$\frac{y_2-y_1}{x_2-x_1}$

⇒ needs any two points on the line (x₁,y₁) and (x₂,y₂)

Let's get the required information:

(x₁,y₁) ==> (0,0)

(x₂,y₂) ==> (5,2)

Let's solve:

$Slope = \frac{2-0}{5-0} =\frac{2}{5}$

Answer: 2/5

Hope that helps!

If cos Θ = square root 2 over 2 and 3 pi over 2 < Θ < 2π, what are the values of sin Θ and tan Θ?

KIM [24]

Answer:

The answer is

$sin(\theta)=-\frac{\sqrt{2}}{2}$

$tan(\theta)=-1$

Step-by-step explanation:

we know that

$tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

$sin^{2}(\theta)+cos^{2}(\theta)=1$

In this problem we have

$cos(\theta)=\frac{\sqrt{2}}{2}$

$\frac{3\pi}{2}$

The angle $\theta$ belong to the third or fourth quadrant

The value of $sin(\theta)$ is negative

Step 1

Find the value of $sin(\theta)$

Remember

$sin^{2}(\theta)+cos^{2}(\theta)=1$

we have

$cos(\theta)=\frac{\sqrt{2}}{2}$

substitute

$sin^{2}(\theta)+(\frac{\sqrt{2}}{2})^{2}=1$

$sin^{2}(\theta)=1-\frac{1}{2}$

$sin^{2}(\theta)=\frac{1}{2}$

$sin(\theta)=-\frac{\sqrt{2}}{2}$ ------> remember that the value is negative

Step 2

Find the value of $tan(\theta)$

$tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

we have

$sin(\theta)=-\frac{\sqrt{2}}{2}$

$cos(\theta)=\frac{\sqrt{2}}{2}$

substitute

$tan(\theta)=\frac{-\frac{\sqrt{2}}{2}}{\frac{\sqrt{2}}{2}}$

$tan(\theta)=-1$

Help me with this please?? Find the indicated side length(s) of this triangle in simplified radical form

miss Akunina [59]

Answer:

b = 5√6

c = 10√5

Step-by-step explanation:

This is a 30-60-90 triangle

the hypotenuse is always twice the short leg

c = 2(5√2)

c = 10√5

The long leg is alway √3 times the short leg

b = √3(5√2)

b = 5√6
