find the missing angles of triangl​

Answer:

11/13

Step-by-step explanation:

3/13, 5/13, 7/13, 9/13, 11/13

3/13

3/13 + 2/13 = 5/13

5/13 + 2/13 = 7/13

7/13 + 2/13 = 9/13

9/13 + 2/13 = 11/13

Answer:

undefined

Step-by-step explanation:

To find the slope of the line between two points, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:

[tex]\frac{(4)-(3)}{(0)-(0)} \\= \frac{4-3}{0-0}\\=\frac{1}{0}[/tex]

However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)

Answer:

C=120 degrees

Step-by-step explanation:

We can use the law of cosines to find an angle when we have all three sides

(7)^2 = (5)^2 + (3)^2 -(2)(5)(3)Cos(C)

49 = 25 +9 -30Cos(c)

49= 34 -30Cos(c)

15 = -30Cos(c)

Cos(c) = -1/2

C=120 degrees

Answer:

x = 4

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

4(x+2)=6x

distribute 4:

4x+8=6x

Subtract 4x from each side:

8=2x

Divide both sides by 2:

x=4

Answer: 24

Step-by-step explanation:

Because if you do 4.80 times 5 you’ll get 24 because each orange cost $4.80

Answer:

the cost of 5 oranges would be $2.00

Step-by-step explanation:

To solve this we need to find the unit rate and when we do this we can solve this problem.  To find that we need to divide 4.80 by 12 once we do that we just have to multiply that number by 5 to get our answer, when you divide you'll get 0.4 and then multiply that by 5 and you'll get $2.00.

Answer:

2.) Infinitely many solutions

3.) No solutions

Step-by-step explanation:

To solve systems of equations graphically, you need to find where they intersect

2.) First put each equation in the form y=mx+b

x-y=6 -> y= x-6

2x=12+2y -> y= x-6

Then, graph each line

Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.

To check, plug a point in from the graph into both equations and you should get 0=0

3.) First put each equation in the form y=mx+b

1/2x-y=4 -> y=1/2x-4

2y=x+6 -> y=1/2x+3

Then, graph each line

Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.

To check your answer, you would one equation as the y in the other equation.

2(1/2x-4)=x+6, then solve for x

Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!

Answer:

25.13 square meters

Step-by-step explanation:

The formula for finding the circumference of a circle is πd or pi times the diameter

Diameter = 8 meters

Pi = 3.14

3.14 times 8 = 25.13

Answer:

3.25

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]equation: \frac{x}{140} = \frac{30}{100} \\reduced: 100x = 4200\\ solved: \frac{100x}{100} = \frac{4200}{100} \\x = 42[/tex]

An equation is formed of two equal expressions. The equation that shows the relationship 30% of 140 is x is x=0.30×140.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that 30% of 140 is equal to x. Therefore, we can write,

[tex]\text{30\% of 140} = x\\\\\dfrac{30}{100} \times 140 = x\\\\x = 0.30 \times 140\\\\x=42[/tex]

Hence, the equation that shows the relationship 30% of 140 is x is x=0.30×140.

Answer:

the second option, a=3 b=3 c=5

Step-by-step explanation:

first I would change them both into an improper fraction:

9/2 divided by 5/4

dividing is the same thing as mulitiplying by the reciprocal of the second number. so you would mulitply 9/2 x 4/5 = 36/10 and then you simplify back to a mixed number 3 6/10, 6/10 can be reduced so the final answer is 3 3/5.

Answer:

so solving the first one we get

y=2x+5

and the second one we get

y=5x+10+1

y=5x+11

substiuting we get

2x+5=5x+11

3x=-6
