Solve for x and find the value of the unknown angle measures.
snow_tiger [21]

Answer:

x = 20

m = 92

n = 68

p = 92

Step-by-step explanation:

x = 20

2 + 3x = 62

-2           -2

----------------

   3x = 60

  -----   -----

    3       2

    x = 20

m = 92

20 + 68 = 88

180 - 88 = 92

n = 68

The vertical angle is 68 degrees

p = 92

Vertical angle is m, which is 92.

Hope this helped.

If r(x) = 3x – 1 and s(x) = 2x 1, which expression is equivalent to (startfraction r over s endfraction) (6)? startfraction 3 (6
viva [34]

The expression which is equivalent to the given ratio of the two provided binary fraction is startfraction 3 (6) minus 1 over 2 (6) 1 endfraction.

<h3>What is the equivalent expression?</h3>

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The given binary functions are.

r(x) = 3x - 1

s(x) = 2x +1

The expression which has to be found out is,

\left(\dfrac{r}{s}\right)(6)=\left(\dfrac{3(6)-1}{2(6)+1}\right)\\\left(\dfrac{r}{s}\right)(6)=\left(\dfrac{18-1}{12+1}\right)\\\left(\dfrac{r}{s}\right)(6)=\left(\dfrac{17}{13}\right)

Thus, the expression which is equivalent to the given ratio of the two provided binary fraction is startfraction 3 (6) minus 1 over 2 (6) 1 endfraction.

CD has the endpoints C(3, 2) and D(–5, –2). Charlie wants to place the point E at the point that partitions this line segment in
Ganezh [65]
So ... notice the picture below... the ratio is 3:1 from C to D, meaning the segment CE takes 3 units, whilst the ED segment takes 1

anyhow

\bf \textit{internal division of a line segment}&#10;\\ \quad \\\\&#10;C(3,2)\qquad D(-5,-2)\qquad&#10;ratio1=3\qquad ratio2=1\qquad 3:1&#10;\\\\\\&#10;\cfrac{C\underline{ E }}{\underline{ E }D}=\cfrac{ratio1}{ratio2}\implies &#10;ratio2\cdot C=ratio1\cdot D&#10;\\\\\\&#10;1(3,2)=3(-5,-2)&#10;\\ \quad \\\\&#10;{{ E=\left(\cfrac{\textit{sum of "x" values}}{ratio1+ratio2}\quad ,\quad \cfrac{\textit{sum of "y" values}}{ratio1+ratio2}\right)}}

\bf \qquad thus&#10;\\\\\\&#10;E=\left(\cfrac{(1\cdot 3)+(3\cdot -5)}{3+1}\quad ,\quad \cfrac{(1\cdot 2)+(3\cdot -2)}{3+1}\right)
