Answer:

B) 6.68

Step-by-step explanation:

Use Cosine.

Cosine= Adjacent ÷ Hypotenuse

In this case the base you want to find is adjacent to the angle, 42°. Hence,

Cos (42)= adjacent ÷ hypotenuse

Cos (42) = x ÷ 9

x = Cos (42) × 9. Input that into your calculator.

x= 6.68

To remember the trigonometric ratios/formulas

Use the acronym, SOHCAHTOA

Hope this helps!!!!

Are 2 by 5 and 4 by 10 equivalent fraction ???

Zinaida [17]

Yes 2/5 and 4/10 are equivalent fractions. This is because you are able to multiple both numbers in 2/5 by 2 and get 4/10. In addition, you can divide both numbers in 4/10 by 2, therefore they’re equivalent.

Find the missing side

Verdich [7]

Answer:

$x=15.56$

Step-by-step explanation:

We can use the law of sines here. However, we will first need to solve for the missing angle.

The interior angles of a triangle add up to 180.

Therefore,

$35+90+x=180$

where $x$ is the missing angle.

$35+90+x=180$

$x+125=180$

$x=55$

So the missing angle is 55 degrees.

Now we can use the law of sines to set up a proportion.

$\frac{19}{sin(90)}=\frac{x}{sin(55)}$

Now simplify the equation.

$x=15.56$

<em>Rounded to the nearest hundredth.</em>

If the value of y varies inversely with x , which function represents the relationship between x and y if y = 48 when x = 3?

kakasveta [241]

Answer:

A. Y = 144/x

Step-by-step explanation:

Inversely means y = 1/x

If y = 48, when x = 3

so 144/3 = 48

Therefore the answer is A
