Answer:

[tex] a = \frac{28}{ \sqrt{2} } [/tex]

Step-by-step explanation:

[tex] \sin \: 45 \degree = \frac{a}{28} \\ \\ \frac{1}{ \sqrt{2} } = \frac{a}{28} \\ \\ a = \frac{28}{ \sqrt{2} } [/tex]

The side of "a" of right angled triangle is  [tex]\frac{28}{\sqrt{2} }[/tex] .

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.

The basic trigonometric ratios formulas are given below,

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

sec θ = Hypotenuse/Base

cosec θ = Hypotenuse/Perpendicular

cot θ      = Base/Perpendicular

According to the question

In right angle Δ

Hypotenuse = 28

Base for ∠45° = b

Perpendicular for ∠45° = a

now , Using trigonometric ratio

sin θ [tex]= \frac{Perpendicular}{Hypotenuse }[/tex]

sin 45° = [tex]= \frac{a}{28}[/tex]

[tex]\frac{1}{\sqrt{2} } = \frac{a}{28}[/tex]

a = [tex]\frac{28}{\sqrt{2} }[/tex]

Hence, side of "a" of right angled triangle is  [tex]\frac{28}{\sqrt{2} }[/tex] .

Answer:

y-1=7(x-0)

Step-by-step explanation:

The line perpendicular to y=-1/7+1 is y=7+1 because you find the reciprocal of the slope.

Then find one point on the line since the equation has a y intercept just use (0,1) and put that into point slope

Answer:

Answer:

si

Step-by-step explanation:

Answer:

m is 3 since it's the slope and b is -2 since its the y-intercept

Step-by-step explanation:

the formula is y=mx+b so 3 is in the m spot and -2 is in the b spot.

Answer:  m = 3 , b = -2

Step-by-step explanation:

y = 3x - 2, we found out m and b by using the form y = mx + b, where m is the number in front of x.

Therefore we found out that m is 3, b is -2.

Answer:

x = 21 and y = 83

Step-by-step explanation:

Since the figures are similar, then corresponding sides and angles are congruent, that is

GE = LA

x = 21

and

∠ I = ∠ M , so

y = 83

Answer:

y-9=7(x+5)

Step-by-step explanation:

Point-Slope form is

[tex]y-y_{1} =m(x-x_{1} )[/tex]

where m equals the slope of the line and y1 and x1 represent the y and x coordinates of one of the points on that line.

First, let's find the slope (change in y divided by the change in x):

[tex]\frac{9-(-5)}{-5-(-7)} =\frac{14}{2} =7[/tex]

Now, let's choose any one of the two points, I'll pick (-5,9), but (-7, -5) also works.

Substitute in the y value (in this case 9) for y1 and substitute the x value (in this case -5) for x1

We can also substitute the slope, m which we know is 7.

y-9=7(x-(-5)

y-9=7(x+5)

It is increasing by 11% for each application.

Answer:

3: D - Undefined

4: A - 1

Step-by-step explanation:

For Question 3 your answer is D, undefined, because it does not have a slope, a slope is like a hill, but that just goes straight up, thus it is undefined.

For Question 4 your answer is A, 1, because it moves one digit to the right and then 1 digit up, Thus that is your answer.

Answer:

252

Step-by-step explanation:

We can use the identity

LCM(a, b) = a * b / GCD(a, b)

GCD(28, 63) = GCD(4 * 7, 9 * 7) = 7

LCM(28, 63) = 28 * 63 / 7 = 28 * 9 = 252

Answer:

their total collected is $135.45

Step-by-step explanation:

travis collect 20% more than Jessica

if travis collect $43 then

20% of 43

43 × 20 ÷ 100 = $8.6

Jessica collected $8.6 less than travis

$43 - $8.6 = $34.4

and Robin collect 35% more than travis

35% of 43

43 × 35 ÷ 100 = $15.05

therefore Robin collect $15.05 more than travis

$43 + $15.05 = $58.05

their total collected

Jessica collected $34.4

robin collected $58.05

travis collected $43

total

$34.4 + $58.05 + $43 = $135.45

320 area hope it helps you

Answer:

56 cm²

Step-by-step explanation:

(4+10)8/2 = 14x8/2 = 112/2 = 56

The slope is the change in y over the change in x.

The first number in the parentheses is the x value, the second number is the y value.

Slope = (0-3) / (4-0)

Slope = -3/4

The y intercept is the y value when x is 0.

The given point (0,3) has x as 0, so the y intercept would be 3

Answers: slope = -3/4, y intercept = 3

Answer:

y intercept = 3 slope = -3/4
