Step-by-step explanation:

since all angles add up to 180:

(8x-1)+(3x+4)+(3x+9)=180

add like terms:

14x+12=180

x=12

Hope that helps :)

T/3 > Solve > 15. Graph the solution 3 The solution is

MissTica

Answer:

$T > 45$

Step-by-step explanation:

Given

$\frac{T}{3} > 15$

Required

Graph the solution

$\frac{T}{3} > 15$

Multiply both sides by 3

$3 * \frac{T}{3} > 15*3$

$T > 15*3$

$T > 45$

Find all polar coordinates of point p if p=1,-x/6

Alecsey [184]

Answer:

All polar coordinates of point P are; (1 , -x/6 + 2nn) and (-1, -x/6 + (2n+1)n)

Step-by-step explanation:

The polar coordinates can be represented as;

(r,Ф)= (r,Ф+2nn) or (r,Ф) =(-r,Ф+(2n+1)n)

Where n is any integer value.

From the question, we are given that; p=(1,-x/6)

Comparing it with P(r,Ф), then r = 1 and Ф = -x/6

The polar coordinates will now be;

P(r,Ф) = (r,Ф+2nn) = (1 , -x/6 + 2nn)

Where; n is any positive integer and the value of r is positive.

While;

P(r,Ф) =(-r,Ф+(2n+1)n) = (-1, -x/6+(2n+1)n) and n is any positive integer and the value of r is negative.

Thus, all polar coordinates of point P are (1 , -x/6 + 2nn) and (-1, -x/6 + (2n+1)n)

Solve for x. X -8 = -11 With step by step explanation or with ur work.

igor_vitrenko [27]

To find:

=> The value of x

=>

$x - 8 = - 11$

Now, we'll move -8 to the other side i.e the RHS side,

which results in the change of it's sign(- converts into +)

=>

$x = - 11 + 8$

Now , we'll add the Numbers

=>

$x = - 3$

<h2>Hence,-3 is the required answer.</h2>
