Answer:

the X is 6 and the uw is 55

Step-by-step explanation:

because the VUW trangle is Isosceles

who do i know because there is right angle and Median and bisector and if this 3 qualities in the trangle its means the trangle is isosceles trangle hope you understand my engilish

Answer:

9x + 1 = 7x + 13

<=> 2x = 12

<=> x = 6

with x = 6, UW = 7.6 + 13 = 55

Suppose PV =NRT, where P=8, V=2X, N=2 and R=2X.you are given X=3. Solve for T

FromTheMoon [43]

Answer: T = 4

Step-by-step explanation:

1. Write all the variables down

P = 8 V = 2X N = 2 R = 2X X = 3

2. Since you know that X = 3 substitute it in to find V and R

V = 2X = 2(3) = 6

R = 2X = 2(3) = 6

3. Find PV

PV = P x V

= 8 x 6

= 48

4. Find NRT

NRT = N x R x T

= 2 x 6 x T

= 12 x T

= 12T

5. Find T

PV = NRT

48 = 12T

12T = 48

divide both sides by 12

T = 48 ÷ 12

T = 4

Find the co-ordinates of the point of trisection of the line joining the points A(1,8) and B(4,2).

Licemer1 [7]

<u>coordinates of the point are (2,6) and (3,4)</u>

Answer:

Solution given:

let the given point be A(1,8) and B(4,2).

P and Q are the two points on AB such that

AP=PQ=QB=k

now

comparing AP and PB

AP=k

PB=2k

ratio of AP and PB = $\frac{1k}{2k}$ = ratio 1:2

now

finding p

for this

$(m_1,m_2)=(1,2)$

For AB

$(x_1,y_1)=(1,8)$

$(x_2,y_2)=(4,2)$

now by using division formula

$(x,y)=(\frac{m_1x_2+m_2x_1}{m_1+m2},\frac{m_1y_2+m_2y_1}{m_1+m2})$

$=(\frac{1*4+2*1}{1+2},\frac{1*2+2*8}{1+2})=(2,6)$

similarly

Q divides AB

Ratio of AQ and QB = $\frac{2k}{1k}$ = ratio 2:1

$(x_1,y_1)=(1,8)$

$(x_2,y_2)=(4,2)$

$(m_1,m_2)=(2,1)$

by using division formula

$(a,b)=(\frac{m_1x_2+m_2x_1}{m_1+m2},\frac{m_1y_2+m_2y_1}{m_1+m2})$

$=(\frac{2*4+1*1}{2+1},\frac{2*2+1*8}{2+1})=(3,4)$
