Work out the angle of x please answer ASAP!!

Given:

The figure of a pentagon.

To find:

The value of the x.

Solution:

We know that, the sum of all interior angles of a pentagon is 540 degrees. So,

(5x-25)+(6x+25)+(6x-3)+(9x)+(7x+15)=540

(5x+6x+6x+9x+7x)+(-25+25-3+15)=540

33x+12=540

Subtract both sides by 12.

33x+12-12=540-12

33x=528

Divide both sides by 33.

x=\dfrac{528}{33}

x=16

Therefore, the value of the x is 16.

What is the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) ?
maxonik [38]
ANSWER

y + 5= - \frac{9}{11} (x-3)

or

y - 4= - \frac{9}{11} (x + 8)

EXPLANATION

We want to find the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4).

The point-slope form is given by;

y-y_1=m(x-x_1)

where

m = \frac{4 - - 5}{ - 8 - 3} = \frac{4 + 5}{ - 11} = - \frac{9}{11}

is the slope of the line.

If

(x_1,y_1)=(3,-5)

The point-slope form is

y + 5= - \frac{9}{11} (x-3)

On the other hand, if
(x_1,y_1)=( - 8,4)

Then the point-slope form is,

y - 4= - \frac{9}{11} (x + 8)

These two equations are the same when simplified.

Please can someone help me. I’m giving POINTS!! Solve for X
KATRIN_1 [288]

Answer:

6

Step-by-step explanation:

By inscribed angle theorem

(15x-23)\degree = \frac{1}{2}[360\degree-(91+135)\degree]\\(15x-23)\degree = \frac{1}{2}[360\degree-226\degree]\\(15x-23)\degree = \frac{1}{2}[134\degree]\\(15x-23)\degree = 67\degree\\15x-23 = 67\\15x = 67+23\\15x = 90\\x= \frac{90}{15}\\x=6

Find the missing dimention of each triangular prism<br><br> 10 ft<br> 3ft<br> V= 30 ft3
kogti [31]
So you first multiply the found dimensions: 10*3 = 30. Now you have to divide by 2 since it is a triangular prism: 30/2 = 15.
30 (the volume) divided by 15 is 2.
Your missing dimension is 2 feet.

Hope this helps,
