Answers

Answer 1

Answer:

Answer: Option (d).

Step-by-step explanation:

it is given that B is between A and C.

Using segment addition property, we get

$AC=AB+BC$

The given values are AB = 46, BC = 12x, and AC = 142.

Substitute these values in the above equation.

$142=46+12x$

$142-46=12x$

$96=12x$

$(96)/(12)=x$

$8=x$

$x=8$

Therefore, the correct option is (d).

Each exterior angle of a regular polygon is 9°Calculate the number of sides of the polygon

Answers

Answer:

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide this by the value of 1 exterior angle to find the number of sides n

n = 360 ÷ 9 = 40

Answer:

Required Answer:-

Let the number of sides=x

Each angle measures 9°

As we know that in a polygon

${\boxed{\sf Sum\;of\:exterior\:angles=360°}}$

Substitute the values

${:}\longrightarrow$ $\sf 9x=360$

${:}\longrightarrow$ $\sf x={\frac {360}{9}}$

${:}\longrightarrow$ $\sf x=40$

$\therefore$ Number of sides=40.

Find the slope and y-intercept of the line.
y = 2x + 5

Answers

y = 2x + 5 is in the form of y = mx + b, where m is the slope and b is the y-intercept.

y = 2x + 5
y = mx + b

m = slope = 2
y-intercept = b = 5

The slope of the line is 2.
The y-intercept of the line is 5.

The slope and y-intercept of the line are 2 and 5 respectively.

How to find the slope and y-intercept of the line?

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

The general form of the equation of a line is y = mx + b,

where m is the slope and b is the y-intercept

We have:

y = 2x + 5

Comparing with y = mx + b:

slope (m) = 2

y-intercept (b) = 6

I hope this helps

or you could....

15 would be the ninth term in this sequence , because you have
