<h2>Greetings!</h2>

Answer:

Angle A is 118°

Step-by-step explanation:

All angles in a circle add up to 180, so this means that all the measurements of the three angles add to 180:

x + 2x + 13 + x - 8 = 180

Clean it up:

3x + x + x + 13 -8

5x -5 = 180

To isolate the 5x, you need to move the +5 over to the other side, making it a negative 5:

5x = 180 - 5

5x = 175

Now divide each side by 5 to get the value of 1x:

$\frac{5x}{5} = \frac{175}{5}$

x = 35

So angle A is:

3x + 13

3(35) + 13 = 118

<h3>So angle A is 118°</h3>

We know, the sum of the measures of angles in a triangle is 180°.

Therefore we have the equation:

x + (x - 8) + (3x + 13) = 180

(x + x + 3x) + (-8 + 13) = 180 <em>combine like terms</em>

5x + 5 = 180 <em>subtract 5 from both sides</em>

5x = 175 <em>divide both sides by 5</em>

x = 35

m∠A = (3x + 13)°. Substitute:

m∠A = (3(35) + 13)° = (105 + 13)° = 118°

Answer;

X = 18: AD = 18

Step-by-step explanation:

Here, we want to find the measure of AD

From the given image;

AB = x + 3

AD = x

AC = 24 + 4 = 28

AE = 24

Substituting these values

we have ;

(x + 3)/x = 28/24

24(x + 3) = 28x

24x + 72 = 28x

28x - 24x = 72

4x = 72

x = 72/4

x =18

You need 23 yards of fabric to make five dresses. How many yards of fabric would be needed to make 8 dresses?

olasank [31]

Answer:

36.8 or 37 yards of fabric

Step-by-step explanation:

23 yards of fabric = five dresses

23 divided by five equals four point six

four point six multiplied by eight dress equals 36.8

23 yds of fabric = 5 dresses

23÷5=4.6

If you need to know how many yards of fabric, then you'd do:

4.6×8

4.6 is the amount of each yards 5 dresses are in and so if you times that by how many dresses you need now, you'll get:

36.8 yards of fabric

To round, it'd be 37 yards of fabric

Given P space equals space P subscript 0 space plus space rho g h, your objective is to determine the uncertainty of P by measur

son4ous [18]

Answer:

the g's contributing term for the overall uncertainty of P is $dP_g = [\frac{dg}{g}]$

Step-by-step explanation:

From the question we are told that

The pressure is $P = P_o + \rho gh$

The first step in determining the uncertainty of P in by obtaining the terms in the equation contributing to it uncertainty and to do that we take the Ln of both sides of the equation

$ln P = lnP_o + ln(\rho gh )$

=> $ln P = lnP_o + ln \rho + ln g + ln h$

Then the next step is to differentiate both sides of the equation

$\frac{d(ln P)}{dP} = \frac{d(ln P_o)}{dP_o} + \frac{d(ln \rho)}{d\rho} +\frac{d(ln g)}{dg} + \frac{d(ln h)}{dh}$

=> $\frac{dP}{P} = \frac{dP_o}{P_o} + \frac{d \rho}{\rho} +\frac{d g}{g} + \frac{d h}{h}$

We asked to obtain the contribution of the term g to the uncertainty of P

This can deduced from the above equation as

$dP_g = [\frac{dg}{g}] P$
