I need help with numbers 2,3,4,5,6 I need to graduate so help

Neporo4naja [7]

Answer:

sinα=√3/(2√7)

cosα=5/(2√7)

tanα=5/√3

cscα=(2√7)/√3

secα=(2√7)/5

*note* you can simplify the above further (by rationalizing them), but I think it's probably fine to leave them as is *

3.) g15.9

4.)25.4

5.) 70.8

6.) 36.4

Step-by-step explanation:

Cot is the inverse of toa so cot= adj/opp

This means the traingle's adjacent side is √3 and its opposite is 5

with this information let's figure out the hypotonouse

√3²+5²=c²

3+25=c²

28=c²

√28=c

√28=2√7

which means the triangle's

opposite= √3

hypotonous= 2√7

Adjacent= 5

With all of this we can just plug in the numbers to find the missing information (where α=angle or theta)

sinα=√3/(2√7)

cosα=5/(2√7)

tanα=5/√3

cscα=(2√7)/√3

secα=(2√7)/5

For this one we have the adjacent and need the opposite

we will use TOA

Tan(25)=x/34

34tan(25)=x

x=15.9

4.) For this one we have the adjacent but need the hypotonouse

we will use CAH

cos(48)=17/x

17/cos(48)=x

x=25.4

5.) for number 5 we have the oppsite and hypotonouse and so we'll use SOH

sin(α)=17/18

α=70.8

6.) For this one we have the opposite and adjacent and so we'll use TOA

Tan(α)=(31/42)

α=36.4

Vonna scored 35 goals at soccer practice. Her ratio of goals to misses was 5:8. How many times did she miss?

Digiron [165]

Answer: She misses 56 times at a soccer practice.

Step-by-step explanation:

Let the goals she misses be 'x'.

According to the question:

$5:8::35:x$

These two ratios follow direct relationship, so:

$\frac{5}{8}=\frac{35}{x}\\\\5x=35\times 8\\\\x=\frac{280}{5}\\\\x=56$

Hence, Vonna misses 56 times at a soccer practice.

What is the equation of the graphed line written in

Andrew [12]

Given:

Given that the graph of the linear equation.

We need to determine the equation of the graph.

Slope:

The slope of the equation can be determined using the formula,

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

Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;

$m=\frac{-4-0}{0-2}$

$m=\frac{-4}{-2}$

$m=2$

Thus, the slope of the equation is 2.

y - intercept:

The y - intercept of the equation is the value of y when x = 0.

Hence, from the graph, it is obvious that when x = 0, the value of y is -4.

Therefore, the value of the y - intercept is b = -4.

Equation of the line:

The equation of the line can be determined using the formula,

$y=mx+b$

Substituting the values, we have;

$y=2x-4$

Subtracting both sides by 2x, we have;

$-2x+y=-4$

Dividing both sides by -1, we get;

$2x-y=4$

Thus, the equation of the line is $2x-y=4$

Hence, Option B is the correct answer.

9) A heptagon has 6 exterior angles with measures of 47, 55, 62, 64, 54, and 49. What is the measure of the interior angle adjac

svetlana [45]

Answer:

seventh interior angle=∠x=29°

Step-by-step explanation:

sum of interior angle of polygon is equal to 360°

let seventh angle of heptagon is x

∠x+47°+55°+62°+64°+54°+49°=360°

∠x=360°-(47°+55°+62°+64°+54°+49°)

∠x=360°-331°=29°

∠x=29°

seventh interior angle=∠x=29° answer
