5. For Which value of x is line L parallel to line m?

laiz [17]

Answer:

$x=22$

Step-by-step explanation:

we know that

If line l is parallel to line m

then

$130\°+(2x+6)\°=180\°$ -----> by supplementary angles (consecutive interior angles)

solve for x

$136+2x=180$

$2x=180-136$

$2x=44$

$x=22$

well, you already know how to convert from mixed to improper, so let's simply do the division.

$\bf -2\frac{1}{2}\div 6\implies -\cfrac{5}{2}\div 6\implies \cfrac{-5}{2}\div \cfrac{6}{1}\implies \cfrac{-5}{2}\cdot \cfrac{1}{6}\implies -\cfrac{5}{12}$

Diagram shows the composite solid formed by a cuboid and a right prism. Trapezium LMNP is the uniform cross section of the prism

kherson [118]

Answer:

MN = 7 cm

Step-by-step explanation:

Well the volume we can separate into pieces

first the ABCDEFGH (? you know this cuboid)

which has a volume of

$V = AB\cdot BC\cdot CH\\\\V = 3*6*(3+JY+4)$

if you ask where does the 4 come from

it comes from LP = KB = YC and JY + YC =JC

$V = 18(7+MX)$

this is because JY = MX

the other volume is of BCNPKLXY (hope you understand which one)

and the volume is

$V = BP*PN*NX\\\\V=8*6*4\\\\V = 192$

and the last one is KYXLMJ (the top "triangle")

the volume is

$V = \frac{LX*XM}{2}*LK\\\\V = \frac{6*MX}{2}*8\\\\V= 6*4*MX\\\\V=24MX$

so now add them up

and has to equal 444

$V_T = 18(7+MX)+192+24MX\\\\V_T = 126+18MX+192+24MX\\\\V_T = 318+42MX\\\\444=318+42MX\\\\444-318=42MX\\\\126=42MX\\\\MX = 3$

and finally we know that MN = MX + XN = 3+4 = 7

so here is our answer MN = 7 cm

a couple of notes

$1.\:\angle LXM = 90\\\\2.\:\angle KYX = 90$

3. the units don't matter due to the fact that everything is in cm

4. see the picture below to get a better idea of which prism I am talking of

5. tell me if you have questions :D

PR is represented by which sketch?

solniwko [45]

Answer:

Step-by-step explanation:

The direction of the arrow has to go the same way as the one in the question, from P to R. Also, the question only has one arrow, so the answer only has one arrow.
