with reference angle x

perpendicular(p) = 3

base(b)= 9

now

tan x = p/b

tan x = 3 / 9

tan x = 1 / 3

x = tan ^-1( 1/3)

The value of the internal angle m from the heptagon is given by the equation m = 141°.

What is the sum of a polygon's internal angles?

The formula returns the sum of the internal angles of a polygon.

The sum of the internal angles of an n-sided polygon is n = 180° (n - 2), where n is the number of sides = angle in degrees

Given the data,

Let's call the polygon a heptagon.

The polygon has n sides, which equals 7 sides.

Now, n = 180 is the sum of the interior angles of a polygon with n sides ( n - 2 )

7θ = 180 ( 7 - 2 ) 

7θ = 180 ( 5 ) 

When we simplify the equation, we obtain 7 = 900°.

A = 900° denotes the sum of the internal angles of the polygon.

And , the value of A = 120° + m° + 148° + 90° + 142° + 130° + 129°

900° = m + 759°

Subtracting 759° on both sides of the equation , we get

m = 141°

Hence , the interior angle ∠B = 141°

Answers

Answer:

49π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 14, so r = 14 ÷ 2 = 7, then

A = π × 7² = 49π cm²

Answer:

49pi cm^2

Step-by-step explanation:

[tex]a = \pi \: {r}^{2} [/tex]

Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7

so

A = pi × 7^2

A= pi × 49cm^2

Pure salt is made up of sodium and chloride. Each gram

sodium is in 55.7 g of pure salt?

24 g

29 g

9 g

90 g

Answers

Answer:

21.8901 g

Step-by-step explanation:

Given that:

1 gram of pure salt contains 0.393 g of sodium

1 gram = 0.393g

Gram of sodium in 55.7g of pure salt will be x

1g = 0.393g

55.7g = x

Cross multiply:

x = 55.7 * 0.393

x = 21.8901

55.7 g of pure salt will contain about 21.8901 g of sodium chloride

The triangles are congruent. Find the measure of x.

Answers

Match up the sides for each triangle using the little marks through the sides

When you do this you see that x corresponds to c on the first triangle.

The 3 angles in a triangle = 180.

Find c by subtracting A and B from 180

C = 180- 29-63 = 88

Now x = c so x = 88

The answer is C. 88

How do I find the y-intercept of a graph? ​

Answers

Answer:

the y intercept on a graph is the line that goes up and down

Step-by-step explanation:

Step-by-step explanation:

Every point on the y-axis has 0 as its x-coordinate. The y-intercept is the point of intersection of the graph and the y-axis.

To find the y-intercept, let x = 0 in the equation of the graph and solve for y. The value of y is the y-intercept.

For example, what is the y-intercept of

2x + 3y = 6

Let x = 0.

2(0) + 3y = 6

Solve for y.

3y = 6

y = 2

The y-intercept is 2.

What is the best estimate of the area of the figure in square inches?

Answers

Answer = 86.135 squared.

To find the area of this figure the best action would to divide it into three different sections, finding the area of each and then adding them all together.

First, find the area of the square in the center, which would be 60in.

Second, find the area of the half circle. You would use the formula for area of a circle. You would divide this answer by 2 since this is only half of a circle. You would get 14.135in.

Last, you would find the area of the triangle. You would multiply both sides and then divide by 2, since it’s a triangle and not a square. Area for this is 12in.

And then you would add all these together.

Answer:

86.1372 -------> 86.1 (Nearest Tenths)
