If the interior angle ofa regular polygon is 162° how many sides does it have​

Mathematics
1 answer:
RSB [31]3 years ago
5 0

Answer:

20 sides.

Step-by-step explanation:

The exterior angle = 180 - 162 = 18 degrees.

Since the sum of the exterior angles = 360 degrees the number of sides

= 360 / 18

= 20 sides.

PLEASE HELP ME ASAP <br><br> Determine the slope of each line:
Sladkaya [172]

Answer:

a=(2/5), b = (-2,6)

Step-by-step explanation:

well slope formula is rise/run. So for the first one you start at the point  rise 2 run 5 and you reach the endpoint. That is how you know you got the correct slope.  (2/5)

For the second one you start at the first point and you cannot go up because it is a negative slope you run 6 till you hit the other point go down 2. Since you go down 2 that would make it -2.  (-2,6)

What is the value of x? Please show step by step.
3241004551 [841]
Start by using trig to find the length of the line LJ

The triangle KJL (big right angled triangle) has been given the following dimensions

Hypotenuse = 8 \sqrt{2}
The adjacent angle is 30 degrees

Since we have the hypotenuse and the  angle we must use the equation 
opposite = Sin(angle) x Hypotenuse

Opposite= sin30 x 8 \sqrt{2}

Opposite= 4 \sqrt{2}

Therefore line LJ is 4 \sqrt{2}


Now look at the smaller right angled triangle (LMJ) 

Hypotenuse is the line LJ which is 4 \sqrt{2}

The adjacent angle is 45

Since we have hypotenuse and angle we must use the equation opposite = sin(angle) * h

therefore 
x= 4 \sqrt{2} * sin45= 4

Which conditional statement has a false converse?
exis [7]

Consider the converses:

a) If two planes have no points in common, then they are parallel. (true)

b) If a point lies on the y-axis, then it has x-coordinate 0. (true)

c) If two angles have the same measure, then they are congruent. (true)

d) If a figure has four sides, then it is a square. (FALSE) (A figure with 4 sides may not even be a plane figure.)

1/b+x=3b/2x^2 - 1/x<br>btw ^2 means square<br><br>​
AlekseyPX

Answer:

x =  \frac{ - 3b}{4}  \: or \: b

Step-by-step explanation:

\frac{1}{b + x}  =  \frac{3b}{2 {x}^{2} }  -  \frac{1}{x}

=  >  \frac{1}{b + x}  =  \frac{3b - 2x}{2 {x}^{2} }

=  > 2 {x}^{2}  = (b + x)(3b - 2x)

=  > 2 {x}^{2}  = 3 {b}^{2}  - 2bx + 3bx - 2 {x}^{2}

=  > 2 {b}^{2}  = 3 {b}^{2}  + bx - 2 {x}^{2}

=  > 3 {b}^{2}  + bx - 4 {x}^{2}  = 0

=  > 3 {b}^{2}  + 4bx - 3bx - 4 {x}^{2}  = 0

=  > b(3b + 4x) - x(3b + 4x) = 0

=  > (3b + 4x)(b - x) = 0

Hence,

x =  \frac{ - 3b}{4}  \: or \: b
