Answer:

Hi...

2x+4+2x-9+x=180

5x-5=180

5x=185

X=185/5=37....so

A=2*37-9=65

B=2*37-4=70

Answer: see explanation

Step-by-step explanation:

Sum of all angles in a triangle is 180

So add all those angles together equals 180.

2x + 4 + 2x -9 + x = 180

Combine like terms.

5x -5 = 180

5x = 185

X = 37

Now plug x in for the angles

A = 2x -9

A = 2(37) - 9

A= 74 - 9 = 65

B = 2x + 4

B = 2(37) + 4

B = 74 + 4

B = 78

Answer:

X = 29.9

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.  

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

Selecting the angle of 18°:

Tangent Ratio:

[tex]\displaystyle \tan 18^\circ=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

[tex]\displaystyle \tan 18^\circ=\frac{X}{92}[/tex]

Solving for X:

[tex]\displaystyle X=92\tan 18^\circ[/tex]

Operating:

[tex]\displaystyle X=92*0.325[/tex]

X = 29.9

Answer:

3 and 2 is 40 and 4 is 140

Step-by-step explanation:

Answer:

measure of angle 4 is 140°

measure of angle 1 is 140° (given)

measure of angle 3 is 40°

measure of angle 2 is 40°

Step-by-step explanation:

We're given that one angle is equal to the measure of 140° (we'll make this one be angle 1)

because of vertical angles theorem, which states that angles that are opposite to each other and are formed by two intersecting lines will be congruent.

So that means that measure of angle 4 will also be 140°

Because of vertical angles theorem, that means that <3 is ≅ to <2 (we can make them be x)

The sum of all the angles will equal to 360° (since it's a full angle)

Here's the equation:

140+140+x+x=360

simplify

280+2x=360

2x=80

x=40°

Which means that <3 and <2 both equal 40°

Hope this helps!

Answer:

The equation of the line with slope m = 2 and passing through the point (1, 1) will be:

[tex]y = 2x[/tex]

Step-by-step explanation:

We know that the point-slope form of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

The formula [tex]y-y_1=m\left(x-x_1\right)[/tex] is termed as the point-slope form of the line equation because if we know one point on a certain line and the slope of that line, then we can easily get the line equation with this formula and, hence, determine all other points on the line.

For example, if we are given the point (1, 1) and slope m = 2

Then substituting the values m = 2 and the point (1, 2)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 2 = 2(x-1)[/tex]

[tex]y - 2 = 2x-2[/tex]

[tex]y = 2x-2+2[/tex]

[tex]y = 2x[/tex]

Therefore, the equation of the line with slope m = 2 and passing through the point (1, 1) will be:

[tex]y = 2x[/tex]

Answer:

x+y< 400

Step-by-step explanation:

x = Number of lawn tickets sold

y = Number of seat tickets sold

We are told that: Fewer than 400 tickets in total were sold.

Hence, this means that, less than 400 tickets were sold.

The symbol for less than = <

Therefore, the equation you could make for fewer than 400 tickets were sold is given as:

x+y< 400

Answer: x+y< 400

Answer:

5/12 x 3/4= 15/8

Step-by-step explanation:

4x³ + 19x² + 29x + 14

= (4x³ + 7x²) + (12x² + 21x) + (8x + 14)

= x²(4x + 7) + 3x(4x + 7) + 2(4x + 7).

= (x² + 3x + 2)(4x + 7).

Hence 4x³ + 19x² + 29x + 14 divided by 4x + 7 is x² + 3x + 2 or (x + 1)(x + 2).

Answer:

Cost of medium iced caramel latte = $3.59

Step-by-step explanation:

Assume;

Cost of medium iced caramel latte = x

Cost of blueberry muffin = y

So,

On Thursday

x + y = 5.18......eq1

On Friday

2x + 3y = 11.95.....eq2

Eq1 × 3

3x + 3y = 15.54......eq3

eq3 - eq2

x = 3.59

Cost of medium iced caramel latte = $3.59

Step-by-step explanation:

-3x + 6 = 18

-3x - 6 = 18 - 6

-3x = 12

x = -4

Answer:

-4

Step-by-step explanation:

-3x + 6 = 18

subtract 6 from both sides

-3x + 6 - 6 = 18 - 6

-3x = 12

divide -3 to both sides

-3x/-3 = 12/-3

x = -4

Answer:

Step-by-step explanation:

9 people want 2 so 9*2=18

8*2= 16 not enough

8*3=24 enough

You can't order parts of a pizza and if you get less there won't be enough so if you get three pizzas there will be enough for all 9 people.

Answer: 3

9 people, each want 2

SO - 9 x 2 = 18

you have 8 slices in each pizza

2 pizzas = 16 (not enough)

3 pizzas = 24 (everyone get 2)

So 3 pizzas

Answer:

The volume of the cone = 101 cubic inches.

Step-by-step explanation:

Given

Radius of the cone = r = 4 in

Height h of the cone = h = 6 in

To determine

The volume in cubic inches rounded to the nearest whole number.

Using the formula to determine the volume of the cone

V = πr²h/3

substitute r = 4, h = 6, and π = 3.142 in the formula

V = (3.142) (4)²(6) / 3

V =  (3.142) (4)² (2)

V = (3.142) (16) (2)

V = (3.142) (32)

V = 100.544

V ≈ 101 cubuc inches (rounded to the nearest whole number)

Therefore, the volume of the cone = 101 cubic inches.
