Let sin(45°)=0.7071.Enter the angle measure (μ), in degrees for cos(μ)=−0.7071.

Alenkasestr [34]

Given :

Let sin(45°)=0.7071.

To Find :

The angle measure (μ), in degrees for cos(μ)=−0.7071 and value equivalent to 360n + , where n is an integer .

Solution :

We know , value of sin x and cos x is same at x = 45° .

Now , cos (-x) = cos(90°+x)

Therefore , μ in given question is :

μ =90°+45°

μ=135°

So , for angle of type 360°n + :

μ = 360°n + 135° .

Hence , this is the required solution .

the graph shows the number of wimbledon championships of several countries. Write the ration that compares the championships won

arlik [135]

Answer:

The ratio that compares the championships won by Australia to the total number won by the United States is equal to $\frac{2}{5}$

Step-by-step explanation:

Observing the graph

we know that

The championships won by Australia are 6

The championships won by the United States are 15

To find out the ratio, divide the championships won by Australia by the total number won by the United States.

$\frac{6}{15}$

Simplify

Divide by 3 boths (numerator and denominator)

$\frac{2}{5}$

Convert to percentage

$\frac{2}{5}=0.40*100=40\%$

that means

For every 2 championships won by Australia the United States won 5

The championships won by Australia are 40% of the championships won by the United States

Mrrafil [7]

Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:

x=5

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−12=−4x+23

Step 1: Add 4x to both sides.

3x−12+4x=−4x+23+4x

7x−12=23

Step 2: Add 12 to both sides.

7x−12+12=23+12

7x=35

Step 3: Divide both sides by 7.

x=5

Answer:

x=5
